The General Blumenthal colliery was a coal mine in Recklinghausen . Field Marshal Count Leonhard von Blumenthal gave the mine its name . The General Blumenthal union was one of the founding members of the Rhenish-Westphalian Coal Syndicate . The mine has a 120-year history and was in operation for over 110 years.

Pit field and geology

The original pit of the Blumenthal colliery is located on the right side of the Emscher in the area of ​​the Horst-Recklinghauser Mulde. The deposit here is riddled with several trending faults . These faults tear the coal mountains to a length of up to 200 meters. In addition, these disturbances result in a throw of 80 meters. As a result, the north wing of the hollow is positioned significantly lower than the south wing. In the middle of the hollow, the layers lie flat; on the southern edge, the layers stand up at an angle of about 36 gons . At the northern edge of the field, the strata dip approximately 59 gons. The thickness of the seams worth building is between 0.75 and 2.75 meters. In the western field, the mountains are torn apart by the Tertius fault over a length of up to 400 meters. This disturbance creates several small cracks . These jumps create seigere faults of up to 600 meters. In this area there are several seams of the gas flame coal section. In the lying part of the field there are both gas flame coals and fat coals . Only a few of the existing and manageable seams in the entire mine field are without mining resources . In the case of the seams with rock material, the strength of the rock material is between 0.1 meters and 0.6 meters.

history

The beginnings

The General Blumenthal drilling company was founded on October 17th, 1869. Already in 1872, the mutation holes found what they were looking for. On May 8th of this year a coal seam was drilled in Recklinghausen Stuckenbusch at a depth of 150 laughs . On March 28, 1873, the first general assembly of the new drilling company was held in the Roman court . On April 22 of the same year, the General Blumenthal I and General Blumenthal II pit fields were awarded . On May 21 of the same year, the election of the mine board took place. Rive von Wolfsbank was appointed the first mine director. One day later the drilling company was converted into the Blumenthal union. On August 3, the two individual fields General Blumenthal I and General Blumenthal II were consolidated into the General Blumenthal field . On September 1st, 1873, the groundbreaking ceremony for the construction of the mine took place.

The creation of the mine

The sinking work for shaft 1 was started in 1873 . The shaft had a shaft diameter of five meters. The water from the sinking work was discharged into the Hellbach. In 1874 the General Blumenthal III field was awarded and the General Blumenthal field was awarded the following year. On April 18 of 1877 which reached the shaft at a depth of 347.25 meters - (284.1 m NN the) carbon . On May 2 of the same year, the General Blumenthal, General Blumenthal III and General Blumenthal IV fields were consolidated. In addition, this year there was a dispute with the neighboring Clerget mine due to the water discharged into the Hellbach . In 1878 the first level was set at a depth of 408 meters (- 334 m above sea level).

The first years of operation

The promotion was recorded in 1879, it was with the removal of the upper Flammkohlenflöze begun. In the same year, the second level was set in shaft 1 at a depth of 467 meters (- 393 m above sea level). On October 17th of the same year, the Clerget colliery reported to the Royal Revierbeamten in Recklinghausen that the wastewater from the Blumenthal colliery at the Lechtappe farm would flow into the Hellbach and that this highly aggressive pit water would damage the boiler systems of the Clerget colliery. After lengthy examinations of the water, the mining authority ordered that the pit water had to be pre-cleaned in a sedimentation basin before it was discharged into the stream. In the following months the sinking work had to be interrupted several times because there were problems with the shaft joints . Due to water ingress, production had to be suspended for six months from April 13, 1880. In 1881 the mine got its own railway connection. In 1883 there was a firedamp explosion at the mine, killing six miners . On January 21, 1884 there was another firedamp explosion that killed 19 people. The explosion occurred in the east field in seams 0 and 1/2. As a result of this mine accident , the underground workforce was reduced by five percent. During the later investigation work it was found that the cause of the explosion was a defective gasoline lamp . The Prussian commission for the investigation of the firedamp drafted a regulation, based on which every mine had to have two mobile shafts. This also improved the ventilation situation in the hard coal mines. In 1889 a coking plant was put into operation. On February 27, 1890, a further shaft, shaft 2, began to be sunk. The shaft was five meters in diameter. The shaft was beside pit one set . On April 18 of the same year, the General Goeben and Werder mining fields were acquired. The entire right now covered an area of ​​19.7 km 2 . In 1891 the sinking work on shaft 1 was resumed and the shaft was sunk deeper. On November 19 of the same year, shaft 2 was penetrated with the first level . The weather management was changed, shaft 2 became a retracting shaft and shaft 1 became an extending shaft.

In 1892, the fourth level was set in shaft 1 at a depth of 570 meters (-508 m above sea level). In the same year, shaft 2 was penetrated with the third level. On February 1st of the following year there was another firedamp explosion in which 20 miners lost their lives. In the same year, shaft 2 was penetrated with the fourth level. On June 22, 1895, the sinking work for shaft 3 began. The shaft had a diameter of 5.6 meters. The shaft was set up near the Recklinghausen train station . The shaft was thus about 2.5 km north of pit 1/2. On November 19, 1896, there was another firedamp explosion on Blumenthal, killing 26 miners. Because of these many accidents, the General Blumenthal colliery was one of the mines with the most firedamp explosions in the Ruhr area. In the same year, the 5th level was set in shaft 2 at a depth of 620 meters (- 558 m above sea level). On May 26, 1897, shaft 3 reached the Carboniferous at a depth of 509 meters (- 428.3 m above sea level). At that time, the mine was part of the Recklinghausen mining area. The weather bed was set at a depth of 408 meters . In the same year, the shaft with the 1st level and the 2nd level penetrated. The coal extraction took place mainly on the 4th level (570mS). This floor was served by shaft 2. The filling points were exposed on the 5th level (620mS) and the southern and northern main cross- passages were driven. In 1898, shaft 1 to the 5th level was in operation. Shaft 2 was sunk down to a depth of 687 meters. On June 1 of the same year, mining began in shaft 3. On August 1 of the same year, the sinking work for shaft 4 began. Shaft 4 was placed next to shaft 3. It was five meters in diameter. On September 28 of the same year there was a serious accident during the cable car trip, in which 17 miners were killed. The reason for this accident was an exaggeration of the conveyor cage . In 1899, the sinking work on shafts 2, 3 and 4 continued. The shaft 4 was penetrated with the 2nd level. In 1900, the 6th level was set in shaft 2 at a depth of 722 meters (-660 m above sea level). In the same year, mining began in shaft 4 and the shaft was further sunk at the same time. In the following year, the third level was set in shaft 4 at a depth of 620 meters (- 540 m above sea level).

The further expansion of the mine

In 1902 the construction of the first coke ovens began on the Blumenthal 3/4 site. In the same year, 19 free shifts had to be taken and 574 employees were laid off. This year, shaft 1 was sunk to the 6th level and shaft 3 with the 3rd level penetrated. In 1903 there was a change of ownership and the new owner was Hibernia AG . However, at the extraordinary general assembly, Hibernia AG initially did not succeed in acquiring all 1000 Kuxe , but only 984 Kuxe. On February 5, 1904, the sinking work for shaft 5 began. At that time, the mine was the deepest mine in the entire Upper Mining District. The shaft was five meters in diameter. The shaft was planned in order to shorten the conveying routes to the gas flame coal sections. In addition, better ventilation of the mine workings should be achieved with the shaft. At the beginning of the same year, the remaining 16 Kuxe could be acquired. As a result, the mine ownership could be re-registered on April 26th . The acquisition of the General Blumenthal colliery also increased Hibernia AG's share in the coal syndicate. In 1904 a coking plant was put into operation on the site of mine 3/4. Due to the high methane content of coal, the methane content in the waste air stream reached a value of 0.48 percent. In the daily production of the mine, this corresponded to an amount of 38,700 m 3 of methane. In the same year, the weather shaft 5 was sunk at Stuckenbusch . At a depth of 316 meters, the shaft reached the carbon. On September 28 of the same year, a stage in the shaft crashed, killing eight people. In 1905, that was mine workings of Blumenthal half with the pit building Blumenthal 3/4 durchschlägig. The breakthrough between the two construction fields took place on the 5th level. In the same year, the first level was set in shaft 5 at a depth of 390 meters and later the third level at a depth of 496 meters. The shaft was then put into operation. In the following year, construction site 1/2 was penetrated on the first level with the shaft. In August 17, 1908, the sinking work for shaft 6 began. The shaft had a diameter of 6.6 meters. Shaft 6, also called shaft Harz, was added next to shaft 1/2. In the same year, the 9th level was set in shaft 2 at a depth of 915 meters (-853 m above sea level). In 1909, the 4th level was set on the Blumenthal 3/4 construction site in the substation. Shaft 1 was penetrated with the 8th level. In 1910, shaft 3 to the fourth level was sunk deeper. In the following year, shaft 6 was sunk to the fifth level.

On March 27, 1912, mining began in shaft 6. On the same day, the coking plant on shaft 6 was put into operation. Only a few months later, on September 27, the coking plant on shaft 5 was put into operation. From 1914, shaft 1 was only used as a weather shaft and the coking plant there was shut down. In 1928 the coking plants in shafts 5 and 6 were stopped. In the same year the breakthrough of the Blumenthal 1/2/6 plant with the Blumenthal 1/2 plant took place on the 4th level. In addition, shaft 5 was abandoned and closed this year. On August 18, 1930, the two Blumenthal plants were merged into one Blumenthal 1/2/6 plant. After the funding merger was completed, funding to Blumenthal was discontinued. Twelve people died in a coal dust explosion on July 3, 1933 on the above- ground reading belt of mine 1/2/6, six of them mining apprentices. On July 3, 1937, there was a firedamp explosion. In this mining accident, 15 miners were killed. On June 6, 1940, the sinking work for shaft 7 began. The shaft was set in the west field about 3.5 kilometers north of the Blumenthal plant 1/2/6. The shaft was six meters in diameter. In the same year, the sinking work on shaft 4 was continued and the shaft was sunk deeper. In the following year, on April 4th, a start was made in shaft 3, starting from the 4th level. The shaft was sunk to the 8th level. On February 15, 1942, shaft 7 reached the Carboniferous at a depth of 502.2 meters. On May 15 of the same year, six miners were killed in a mine fire on mine 1/2/6. On February 17, 1943, the new pit ventilator was put into operation at shaft 7 . Alignment of the 8th level began in the same year . In the following year, shaft 7 was put into operation as a new weather shaft.

The further operation

Towards the end of the Second World War, on the orders of a Gauleiter, all important technical systems ( hoisting machines , boiler houses, etc.) at the General Blumenthal mine were to be blown up so that they did not fall into the hands of the war opponents. The executives resisted this order and so the mine was able to survive the end of the war unscathed. After the war, the mine was subordinate to the Allied occupying powers. In 1946, operations were resumed and the 7th level became the main production level . In 1949 the west field with shaft 5 was abandoned. In 1950, the excavation of the first eastern straightening section began from the 5th cross passage in order to develop the gas coal seams of the Zollverein Group above the bottom. In the same year, shaft 3 received a new hoisting machine. In addition, the washhouse at shaft 3/4 was enlarged. In the following year, the wooden pit lining began to be replaced with punches and caps made of steel. In the same year three blind shafts were sunk. Gas extraction was installed in July. In addition, a planing system was used for the first time at the mine . From 1952 the extracted mine gases were burned in the boiler house and used to generate hot water. An investigation section was driven from the König Ludwig colliery into the Blumenthal field. The excavation of the investigation section, which was approved up to the Blumenthaler jump, was used to explore Eisenstein camps . In 1953 work began on converting the coal washing plant.

In 1954, the sinking work on shaft 7 was resumed and the shaft was sunk to the 7th level. This measure was intended to further open up the deeper parts of the deposit. It was also intended to improve ventilation and underground transport. To the more than two meters powerful seam Zollverein 1 in Verhieb to take the transport of the offset mountains had to be ensured. For this purpose, a downpipe was installed in shaft 2 and a mining bunker installed underground . From April 1, 1955, work began on setting up and setting up the eastern field. The track promotion ran in 1955 partly with locomotives but partly also with pit horses . In the mining sections the material is conveyed by means of a tractor reel . In the following year, shaft 3 reached a depth of 1013 meters. In August of the same year, the compressor system for high-pressure locomotives on the Blumenthal 3/4 operating section was shut down and the compressed air locomotives that were still in existence were replaced by electric locomotives. In addition, the first face at the mine was equipped with a planing system and put into operation. Both the material transport and the coal extraction were carried out via a newly constructed blind shaft. The coals were conveyed via a spiral chute to the 7th level and from there to the shaft. In 1958, the rights covered an area of ​​24.2 km 2 . In 1959, a shearer loader was put into operation for the first time in an attempt on the 8th level in the Hugo 1 longwall face to the east . However, the experiment was terminated after a few weeks due to constant problems with the hanging wall. In coal mining, a scraper chain conveyor was used for the first time this year instead of the shaking chutes used up until then .

In 1960, shaft 5 was finally abandoned. In the same year, the longwall construction began to be converted from hydraulic single -ram support to 5-ram traveling piers. In 1962, the mining directorate to shaft 2, the West field on the fifth floor decided to throw off . The reason for this was the high costs at which the gas flame coals were obtained there. This year, the mine’s degree of electrification reached 79 percent. Gradually, all machines powered by compressed air were replaced by those with an electric drive. In the autumn of 1963, a bottom loader was used for the lowering work for the first time . The first use of this loader took place on the 4th level in the 4th straightening section. In 1964, shaft 5 was filled . In the same year, work began on an additional weather shaft, shaft 8. The shaft was set up in Oer-Erkenschwick on Johannesstrasse, seven kilometers north of Blumenthal 1/2/6. The following year, the decision was made to modernize the mine. For this purpose, the seams that are still steep in the Shamrock field should not be mined any further, but the mining should be concentrated on the Blumenthal mine field. In the same year the belt drive was set up on some conveyor belts . In 1965, the excavation of a connection to the Shamrock colliery began . The drive up took place on the 6th level through the fields of Recklinghausen, Julia and von der Heyd. The route was necessary to connect the two mines, because the Shamrock mine had a much more modern shaft than Blumenthal. In the same year, mining began in the eastern field. Special transport tubs were used for long-distance transport. In the mining operations, stepping-up supports were increasingly used.

On June 22 of 1966, the last acted pit pony in the mine his last film and was then again on day brought. In the same year, the preparatory work for a weather connection to the connection route to Shamrock was carried out at shaft 1. For this, the old fixtures had to be stolen and parts of the shaft extension had to be replaced. In the same year, shaft 8 reached the Carboniferous at a depth of 596.4 meters. In order in the 4th straightening section unlock a up to 2.8 meters powerful Esskohlenflöz the 7th floor and above the sole 7, was used for the Drift excavation a continuous miner used. In 1967, which was the breakdown for coal mine Shamrock in 03.04.11 Herne on the 7th floor created. From then on, production took place at the central conveyor shaft 11, which previously belonged to the Shamrock colliery. Shaft 8 was equipped with a steel box strut headframe . Like all Hibernia AG mines, the General Blumenthal colliery was incorporated into Ruhrkohle AG in 1969 . The mine was affiliated to Bergbau AG Herne / Recklinghausen. In the same year, the weather shaft 1 between the 5th level and the 7th level was expanded to a clear diameter of five meters. Shaft 8 reached its preliminary final depth of 982.5 meters. Due to the heavy wear on the rails of the tracks in the connecting line and the wheels of the trains, there were major disruptions in conveyor operations in 1968. Since the worn rails had to be replaced, the track systems were comprehensively revised and repaired. Once these repairs had been completed, production operations on the link went back to normal. In 1970 the breakthrough and weather network to the Recklinghausen colliery took place . At the end of the year, a radio-controlled overhead monorail was put into operation for the first time on the 5th level . In the steep seams on the 7th level, attempts were made to mine the seams there by means of rotating extraction . The aim of these tests was to build a fully automatic mining drilling machine.

The extension to the north

The first investigations into the An der Haard field began in 1971. However, the plans to mine coal under the forest area on the Haard and to also dig shafts in the forest area met with rejection from part of the population. A further expansion of the construction site towards the north was not possible due to the Haltern reservoir located in this area . In the same year, the establishment of a funding network for the neighboring Ewald mine was started. In order to enable the network, a two-kilometer stretch had to be driven and a bunker system had to be built for the extraction. In addition, a rock mountain had to be driven up to the fourth level in the Ewald. The extraction capacity of shaft 11 and the processing capacity had to be increased. In 1972 a floor conveyor was put into operation from the 7th level over a rock mountain to the Karl seam. A material station was built on level 7 for material handling. The rock mountain also served as a conveyor mountain for the coal mined in the Karl seam. The mine celebrated its 100th birthday on April 24, 1973. In order to reduce the development of dust in the struts, the planer lane spraying was used in the planer struts from 1974. A new headframe was built on shaft 4. Further exploration work was planned for the Haard / Haltern field. In the same year the breakthrough with the Ewald colliery took place on the 7th level. In addition, the funding network with Ewald was completed this year. The mining of Ewald continuation has now been taken over by Blumenthal underground. In addition, the production in shaft 2 was extended to the 9th level. For this purpose, the shaft was equipped with new hoisting ropes and new hoisting cages.

On January 1st, 1977, Ruhrkohle AG was restructured and the number of management companies was reduced to three. The Blumenthal colliery was assigned to the newly founded Bergbau AG Lippe. In the same year, the sinking work on shaft 8 was resumed and the shaft was sunk deeper. Shaft 6 was penetrated with the 7th level. The planning work for the Haltern construction site continued this year. Solutions were worked out in order to be able to optimally develop the fields of Haltern. For this purpose, it was planned to drive the route that had to be driven from shaft 8 to the Haltern construction site with a full-face machine. At this point in time, the rightful rights covered an area of ​​99.8 km 2 , the construction site covered an area of ​​55.5 km 2 . In order to align the Haltern field, the sinking work for the Haltern 1 shaft began in 1979. The shaft was intended to be used for material transport and for cable travel . The groundbreaking ceremony for the new shaft took place on February 1st of the same year. The uppermost area of ​​shaft 1 was created using the freezing process . In the same year, the 10th level was set in shaft 8 at a depth of 1083 meters (-1020 m above sea level). In the same year, the shaft reached a depth of 1129 meters. As of this year, the mining operations started to stabilize the line seams with roadside embankments. In 1980 the sinking work for the Haltern 2 shaft began. The shaft was set up next to shaft Haltern 1. In the same year, the alignment work began in the Haltern field. Both shaft Haltern 1 and shaft Haltern 2 were sunk with a diameter of eight meters.

The other years until the Verbund

In 1981 the Haltern 1 shaft reached the Carboniferous at a depth of 846 meters. In the same year, the first level (marl sole) was set at a depth of 870 meters. For the Haltern 2 shaft, the preliminary shaft to the final depth of 47.8 meters was completed by May of the same year. The shaft was created using the freezing process , for which the freezing machines were put into operation from mid-August. In the same year, the marl bottom was driven from the Auguste Victoria 6 shaft to Haltern 1/2. In the following year, the second level was set in the Haltern 1 shaft at a depth of 1000 meters (- 893 m above sea level) and the third level in the same year at a depth of 1103 meters (- 1010 m above sea level). On March 3 of the same year there was an open pit fire in the Blumenthal construction site , and the fire was extinguished by the mine rescue team. In 1983, at the Haltern 1 shaft on the marl bottom, the filling location sections to the east and west were driven. The shaft bell was built on the second level. In the same year, the Blumenthal 1 shaft was abandoned. At the level of the 3rd level, a breakthrough was created between the Haltern 1/2 construction site and shaft 8. The distance driven had a length of 9.4 kilometers. Shaft 1 was sunk to its final depth of 1135 meters and the shaft sump was created at this depth . The filling points of the shaft were designed for material handling and the cable car. The Haltern 2 shaft reached a final depth of 1112 meters.

In 1984 the sinking facilities at shaft 1 were dismantled and the conveyor systems were installed. On June 28th of the year the final inspection of the shaft took place. The shaft received a hoisting machine with an output of 2600 kilowatts. The conveyor system was designed for a payload of 20 tons. The traction sheave conveyor worked with only one basket with a counterweight. In addition, shaft 2 was put into operation as a weather shaft. In the same year, extraction began in the Haltern field. The mined coal was conveyed from the 3rd level of Haltern to the 7th level of Blumenthal via a mountain belt . From there the coal was transported to shaft 11 and from there to the surface. In 1985 the wash basin and the central building were completed on Haltern 1/2 . A turbo compressor with a capacity of 20,000 m 3 of compressed air was installed for the compressed air supply. The waste heat from the compressor was used to heat the chews. In the same year the Haltern 1 shaft was opened for rope travel . On September 20, the connection mine in Haltern was officially put into operation in the presence of the then Federal President Richard von Weizsäcker . Planning for the Haltern 3 shaft began that same year. The shaft was to be set up in Flaesheim.

In 1986 the battery charging room was further equipped on the third level. During this period, four rock mountains and seven alignment sections had to be excavated in the entire mine field . In the same year, approval was given to expand the tailings pile at shaft 8. Convergence measurements were carried out in the area near the shaft . In the following year, the coal types were separated on the 7th level at the existing loading point. This was achieved through the commissioning of a separate gas coal loading point. Since it was planned to merge the General Blumenthal colliery with the Haard mine, the first preparations for this began this year. In December of the same year, the Haard mine began to drive a rock mountain to the Emscher-Lippe 6 shaft. The rock mountain was needed to solve the weather accordingly . In 1988 the mine field was meanwhile 108 km 2 in size . In the same year a roadheading machine was used on Blumenthal to excavate a seam mountain in the Zollverein 2/3 seam. In order to give priority to drinking water supply, the Haltern field refrained from mining around 30 million tons of hard coal. In the period from January to November 1990, a 140 meter long straightening section was driven on Haltern 1/2 on the 2nd level . The route had a cross-section of up to 32 m 2 . In July of the same year, the Haltern rock mountain was penetrated by the Emscher-Lippe 6 shaft. The shaft was then filled below the breakthrough . In 1991, the special operating plans for the effects of the dismantling in construction site B1 North were submitted. In the same year the kaue at shaft 7 was closed. On October 1, 1992 the General Blumenthal colliery was merged with the Haard mine (formerly Ewald colliery, continuation ) to form the Blumenthal / Haard mine . On January 1, 1993, the two mines were also administratively merged.

Promotion and workforce

Shaft 7 of the General Blumenthal colliery - as it is today

The first production figures come from the year 1879, in that year 7254 tons of hard coal were produced . The first workforce figures come from 1881, in that year there were 147 employees on the mine who produced 24,916 tons of hard coal. In 1885, 303 employees produced 76,551 tonnes of hard coal. In 1890, 199,544 tons of hard coal were extracted; the workforce in that year was 1,045. In 1895, a total of 325,036 tons of hard coal were mined with 1261 employees.

In 1955, a production of 273,275 tons of hard coal, the workforce was 716 employees. In 1960, 4,335 employees produced 1,470,000 tons of hard coal. In 1965, 1,474,850 tons of hard coal were extracted and the workforce was 3,622. In 1970, production exceeded the two million tons mark. This year, with 4,222 employees, a production of 2,277,657 tons of hard coal was produced. In 1976, 2,550,000 tons of hard coal were extracted. In 1980, 4125 employees produced 2,450,123 tons of hard coal. The maximum production of the mine was achieved in 1982. With 4,183 employees, 2,606,249 tons of hard coal were extracted. In 1990, 4043 employees produced 2,377,615 tons of hard coal.
