The Hannover colliery in Bochum was a coal - mine and is now a site of the Westphalian Industrial Museum of the Regional Association of Westphalia-Lippe . The mine had a total of six shafts , which were combined in two shaft systems (1/2/5 and 3/4/6).

On June 14, 1847, the manor owner Karl Richard von Hymmen in Kaiserswerth and the merchant Julius Möller in Elberfeld were granted prospecting permits in the rural community of Hordel . A test drilling with the six brothers drilling rig on the site of the farmer Schulte-Schünen called Ahmann reached the coal mountains at a depth of 92 meters . The political conditions initially interrupted further encouragement . On December 29, 1854, hard coal was found again on another drilling rig, Six Sisters . In the years 1854/1855 the license was granted for the fields Six Brothers , Wupperthal , Anton Ernst and Six Sisters . The size of the field was 4.16 square kilometers. 1856 bought Hannoversche Bergwerksgesellschaft host Mann & Co. AG , the Berechtsame for the mining field . On March 1, 1857 with the sinking of the shaft Karl (Tray 1) started. Four months later, the sinking work began for shaft 2, 50 meters to the south, which was given the name Christian (later Hermann). The sinking work was accompanied by water ingress and financial problems. The Hostmann family had to sell the mine field to the Hanoverian mining company Böstighaus & Co. in 1860 . But even this society lacked the capital to get through the high investments for the construction of the colliery. The company was sold in 1868 after an unsuccessful auction attempt for 30,000 thalers and debt assumption of 317,000 thalers. The Hannoversche Bergwerksgesellschaft zu Bochum took over all Kuxe .

In the years 1859 and 1860 the sinking of shafts 1 and 2 reached the coal mountains. Two massive Malakow towers with a nacelle in between for the two hoisting machines were built above the shafts . Shaft 1 reached the first building level in 1870 at a depth of 162 meters , and regular extraction was established. The Franco-Prussian War of 1870/1871 brought an economic upswing, so that the colliery made a profit for the first time.

On June 27, 1872, the little significant colliery was Alfred Krupp at a price of 5,649,000 Mark acquired and expanded. The shafts were to 304 meters depth geteuft , being in the marl zone with tubbing were lined. The wash basin , the loading bridge and the workshops were expanded above ground . Gas lighting was installed and a water pipe was laid.

In the area of ​​the community of Günnigfeld, the sinking work for shafts 3 and 4 began on October 13, 1873. The following year, the coal mountains were reached. The first colliery colony was built in 1874 on Friedrichstrasse in Eickel; The colony on Derfflingerstrasse was established in 1872–77.

The period from 1873 to 1887 was marked by the founder crisis , ie by economic decline and a sharp drop in coal prices. Due to the secured purchase of coal by Krupp, the development did not have such a drastic effect on the economic situation of the Hanover mine. In 1876, the conveyor was moved from the 161-m level to the 234-m level.

In underground operations, the coal production was changed from the floating pier construction to the floating pier construction. 1881 was the mountain misalignment introduced to the surface cuts to reduce.

A significant innovation in the construction of the conveyor system came from mine director Carl Friedrich Koepe . The rope routing was changed at shaft 2 in 1878 . The hoisting rope was led around the traction sheave and returned to the shaft via a second sheave . It was arranged as an endless rope. Two conveyor baskets were attached, which were guided on staggered guide rails . The arrangement of the conveyor baskets was chosen so that one of the baskets hung at the level of the deepest conveyor floor while the other was at the height of the suspended bench . The weight of the hauling rope was compensated for by the freely hanging lower rope. The conveyor machine only had to compensate for the torque of the different loading of the baskets. With this design, the rope wear and thus the risk of rope breakage has been significantly reduced. This rope arrangement was named Koepe- Förderer after its inventor .

In 1888 the carrier on shaft 2 was replaced. Based on a suggestion by Carl Friedrich Koepe, the machine was installed in the shaft tower. The steam hoisting machine had a cylinder diameter of 980 and 1440 mm with a cylinder stroke of 1570 mm. The machine was designed for a steam pressure of 4.5 atü . It was initially conveyed from the 384 m level with a maximum speed of the conveyor cage of 13 m / s. The basket could accommodate 6 trolleys on 3 floors . The machine was in service for 40 years until the end of the 1920s, when it was scrapped.

Hanover was 1892 Oberbergamt District , the first coal mine, a distance conveyor with Dortmund cable cars , which replaced established the horses promotion. In the same year, the capacity of the conveyor systems on shaft 1 was significantly increased. A stronger compound steam winder was installed and the extraction devices at the filling point were improved. The production shift output of the shaft was increased from 400 to 750 t. As a measure against coal dust explosions, sprinkling of the mine workings was introduced at the time .

In 1891, the mine administration bought the manor Dahlhausen with 469 acres of land and nine more farms. Residential development was planned here.

Union of the Hannover and Hannibal collieries (1899–1918)

After the neighboring Hannibal mine was taken over by Krupp, the two mines were merged in 1899. In 1905, the sinking of shaft 5 next to shafts 1/2 began, which was completed in May 1908 with two promotions. In the same month, the new coal washing machine was put into operation on plant 1/2, which replaced the old washing machine from 1878. The increased demand for steam was covered by a new boiler system. Until 1907, electricity was only generated to a small extent and used exclusively for lighting. Otherwise only steam was available as an energy source. The underground dewatering was also carried out by steam engines. Compressed air was not available.

After its construction in 1907, coke oven gas generators were also installed in Power Plant 1 to supply electricity. The power plant was connected to the power grid of the Rheinisch-Westfälische Elektrizitätswerke in order to be able to draw electricity from it in the event of operational disruptions. However, the coke oven gas generators did not prove themselves and were replaced by steam turbo generators . Since electrical energy was now available, a central drainage system with six electric centrifugal pumps with an output of 30 m³ / min each was installed on the 515 m level .

In 1905 the construction of a settlement with 715 civil servants 'and workers' apartments began in the Dahlhauser Heide settlement on the site of the former Dahlhausen manor. This included a spacious hall structure. The houses were built in the garden city style - some with half-timbered gables. The buildings for civil servants 'and workers' apartments were laid out separately. The working-class families lived in semi-detached houses with extensions for stables, which enabled small livestock to be kept and thus partially self-sufficient.

The Hannibal colliery sank shaft 3 from 1901 to 1903 and shaft 4 from May 1914 to May 1915. Before the First World War , the mines experienced a great boom. At the beginning of the war, many skilled miners were drafted into the military; however, the losses were subsequently offset. There was a huge need for coal and coke for arms production.

Weimar Republic until destruction in World War II (1918–1945)

After the war, the restless political situation, inflation and the occupation of the Ruhr area in 1923 impaired production. Passive resistance was exercised during the occupation; all companies were on strike. Only work that was absolutely necessary to maintain operability was carried out. As a result of the war, working hours underground, including entry and exit, were reduced to 7 hours. The funding quotas fell and there were wage disputes.

As a result of the economic decline, the mines experienced a significant drop in sales and had to lay off miners. Of the approximately 9,000 employees, 2,769 remained until October 1932. Therefore, in 1932, the plant management made the decision to combine the subsidies at the Hanover-Hannibal mine; she had already been set on Hannibal 2 in 1926. After extensive preliminary work underground, on February 28, 1932, production at the Hannover 3/4 mine in Günnigfeld was also given up. The two shafts were also used for ventilation. Shafts 3 and 4 had a final depth of 615 meters, shaft 6 of 950 meters. Hanover 1/2 was expanded as a production location. Shaft 5 initially took over the main production.

The need for electrical energy had increased significantly at the beginning of the 20th century. In 1921 a new power plant was built on Hanover 1/2, which replaced the old power plant. Initially 24 two-flame tube boilers were installed, which were soon replaced by four vertical tube boilers with a steam output of 10 t / h each. Three turbo generators with a total of 13 MW were available to generate electricity . In 1921 the electric light was introduced, which replaced the petrol safety lamp.

In 1929/31, underground transport in Hanover was switched from cable cars to diesel locomotives.

After 1933 major modernizations took place; A new loading facility was set up on Hanover 1/2 and the coal washing facility was rebuilt so that gas and fatty coal could be washed separately. Shaft 2 was subsequently rebuilt and deepened to the 950 m level; the sinking work was completed on December 15, 1938. A year later, the Malakow tower above shaft 2, which consisted of brick masonry with a wall thickness of 2.50 meters, was demolished. The new shaft building with the tower hoisting system could only be put into operation after the Second World War.

The coal sieving and loading was equipped with four rotary luffers in 1936 , which were connected to the shafts 2 and 5 via a carriage circuit. The coal washing plant was rebuilt and modernized in 1938/39. The throughput was increased to 400 t / h.

A firedamp explosion on mine 1/2/5 on September 23, 1939 resulted in 20 deaths and 19 miners injured. As a result, there was a pit fire , so that entire departments had to be bricked up in order to interrupt the oxygen supply to the source of the fire.

Another innovation was the first use of a coal plow in the Ruhr mining industry in August 1942 . The impetus came from the works director Bergassessor Lange. The Schnellhauer, manufactured by the Westfalia Lünen union , was in use without interruption until the Hannibal colliery in the Flöz President was destroyed in the war. The coal plow is pulled in one direction along the coal face using ropes and winches and the coal is peeled off. When the planer moves back, the alley is cleared of the coal and the coal is pushed onto the conveyor via a ramp. After one pass, the plane is pressed back against the coal face by hydraulic rams. The expansion of the longwall in the 1940s was still done with wood.

Before that, the pneumatic pick hammer was mainly used to extract coal, which was the cause of illnesses among miners. In addition to increasing the shift performance, an argument in favor of using the planer was that it would make the work of the cutter easier and maintain the labor force.

When driving the straightening section between the two shafts of the Hanover colliery on the 950 m level led to considerable water ingress, and parts of the colliery were flooded down to a depth of 850 m.

During the war, up to 2,000 forced laborers worked on the mine. Funding from the Hannover-Hannibal colliery was essentially maintained until mid-1944. 31 air strikes were carried out on the pits, with 500 high explosive and 5,000 incendiary bombs hitting the daytime facilities. The mines were badly hit in the air raids on July 25th and November 18th, 1944. The Hannibal colliery was almost completely destroyed and Hanover was badly damaged. At the Hannibal plant, production came to a standstill from November 1944 to June 1945 because the daytime facilities were completely destroyed. Only the aid conveyance on Hannibal 4 was still operational, while the other four conveyance machines on shafts 1, 2 and 3 were badly or completely destroyed. Of the 28 steam boilers , only four could be put back into operation for a short time after the war. On Hannover 1/2, the dormitory for apprentices built in 1940 and the mine rescue house had been completely destroyed. The masonry of the Hannibal 1 shaft was washed out by uncontrolled inflow of water. In order to ensure the stability of the neighboring shaft 5, shaft 1 was filled to a depth of 400 meters and then the shaft was sunk again to the level of 750 meters. The war damage amounted to 47 million Reichsmarks.

On April 10, Bochum was occupied by American troops and the mines were placed under American supervision, which lasted until 1948.

Post-war period and reconstruction (1945–1953)

The two high-pressure steam boilers in the Hanover power plant and the steam and compressed air supply were repaired as a first measure. Furthermore, the southern production of shaft Hannover 5 was rebuilt and the damage to the mine ventilator shaft Hannover 1 was repaired.

Battery II of the Hanover coking plant could be started up again on April 13, 1945 and the delivery of coke oven gas to the city of Wanne-Eickel was resumed on September 22, 1945. At the Hannibal plant, the war damage was repaired on 19 flame tube boilers in order to secure the steam supply for the hoisting machines and air compressors. However, the Hannibal coking plant was not rebuilt because it was completely destroyed.

On December 18, 1947, the four-rope production, which had not been implemented during the war, was put into operation for the first time in the world at the Hanover 2 shaft. The new conveyor system was designed in a forward-looking manner for a final depth of 1400 meters, with a payload of the cage of 12 tons. In the case of a single-rope version, a rope diameter of 90 mm was calculated. It was feared that this rope diameter would no longer be able to be handled. Dangerous twisting forces were feared, which could lead to strong friction between the cage guide and guide rails and cause them to wear out quickly. Hence the innovation to transfer the forces to several ropes. In addition, it was now possible to dispense with a safety device for the conveyor cage , since if a rope breaks, the remaining ropes are still sufficiently dimensioned to hold the cage . Leading the way in this development was the director of the Rossenray mine, chief engineer Otto Wülfing.

In 1947, the most serious war damage to the Hannover 1/2/5 and Hannover 3/4 facilities was repaired. The third high-pressure boiler of the Hanover power plant, which was no longer completed during the war, was put into operation. At the end of 1947, battery 1 of the coking plant could be heated.

High-pressure compressors were installed on the Hannibal mine, which reached a final pressure of 200 bar and were intended to supply the storage tanks of the compressed air locomotives underground. With sufficient capacity of high pressure air, the locomotive drive was switched from diesel fuel to compressed air underground . In addition, a new wash house with a magazine and lamp room was built on the Hannibal facility.

In 1949 the 950 m level was prepared in Hanover and shaft 2 was temporarily shut down for further drilling. A fourth high-pressure steam boiler (80 t / h at 84 bar) was started up at the Hanover power plant. Then the old and uneconomical four vertical tube boilers could be shut down. In 1951, the furnaces of boilers VII and VIII were converted from grate firing (Martin grates) to dust firing with liquid slag discharge.

The mine track networks of Hanover and Hannibal had different gauges . After long planning and as part of the restarting of the Hannibal 1 shaft with the associated wagon circulation, the gauges were adjusted in 1949. An electrically driven turbo compressor for the compressed air supply was installed on the Hannibal plant, so that the old steam-driven compressors were only used as reserve units.

The Hanover coking plant was expanded further in 1949 and operated as the central coking plant. In 1950, the extraction of the 950 m level could be started at shaft 2 (four-rope extraction). A modern land sales point was put into operation on Riemker Strasse.

During the period of reconstruction, the mines continued to be managed by the director Fritz Lange, whose position was later taken over by Erich Ricken.

The post-war period saw the construction of living space in particular. In 1952, a health center for employees was built at Wanne-Eickel-Süd station on Magdeburger Strasse.

In 1952, long-distance steam lines were moved from the Hanover power plant to Hanover 3/4 and Hannibal so that the old boiler houses could be shut down. The training workshop was rebuilt on the Hannibal II mine and a larger workshop building was built.

Founding of the hard coal mine Hannover-Hannibal AG (1954–1967)

Pit field of the Hannover-Hannibal colliery after the affiliation of the Koenigsgrube colliery

As part of the unbundling of German industry by order of the Allies , the hard coal mine Hannover-Hannibal AG was founded on February 16, 1953. The Koenigsgrube colliery was directly adjacent to the fields of the Hannover-Hannibal mine and the Hanover 1/2/5 daytime facility and the Koenigsgrube were right next to each other. The owner of the Königsgrube colliery was Deutsche Erdöl AG in Hamburg, which also owned the Bismarck mine . The daytime facilities of the Königsgrube colliery were out of date after the war and modernization would have meant a lot of effort. Therefore, Deutsche Erdöl-AG was interested in selling the mine. The hard coal mine Hannover-Hannibal AG bought the Koenigsgrube colliery for 21.1 million DM. The purchase was very interesting, as the old fields of Hannibal and Hannover were partially mined to a greater depth , while the Koenigsgrube colliery still had a minable coal supply of 80 Mill. Tons to a depth of 1200 meters. Thus, the total stock could be doubled after the merger. Before mining, the fields of the Königsgrube colliery had a coal reserve of 40 t / m² surface; this is well above the Ruhr area average. The pit fields of the connected pits had an area of ​​11.3 km². In 1955, a cross passage from Hanover to the Königsgrube was driven underground on the 750 m level .

From then on, only the coal mined in the upper layers was extracted from the Gustav shaft of the Königsgrube colliery. This was the gas flame coal and gas coal, which was mined on the 150 m and 250 m levels and transported over days to the Hanover colliery for processing. The coal extracted here was strongly fused with the mountains and had a high proportion of mining . The coal mined at a greater depth was turned to the level of the cross passage on the 750 m level and brought to the surface via the Hannover 5 shaft. In the lower seams of Hanover and Hannibal, fat coal and in some cases even edible coal were mined in the mid-1950s . After the unification, it was the economic goal of the mine management to centralize the extraction and processing on the Hannover 1/2/5 plant and to achieve a common mining level in all fields in the long term. However, the planned 1150 m level was no longer driven.

In 1955 there was a large exchange of space with the city of Bochum. The coal reserves in the eastern field of the Hannibal colliery in the area of ​​the Riemke collecting station had already been severely depleted, while in the northeastern area (location of the former Nosthausen estate ) in the area of ​​the 2nd and 6th eastern sections there were still considerable coal reserves. The exchange of space prevented further settlement there, so that the risk of major mountain damage with high consequential costs could be averted. The hard coal mine Hannover-Hannibal AG thus had a land ownership of 510 ha (212 ha built, 298 ha undeveloped area). In the area of ​​the Hanover and Königsgruber fields, copper deposits were also suspected , the prospecting rights of which have been awarded to the mining company as fields Primus 1 and 3 by the Dortmund Oberbergamt . However, there was no reduction in the copper stocks.

At the end of the 1950s, the bottom was better connected by sinking a few blind shafts . Depending on the part of the field, mining took place in flat and steep seams. In 1954, the lower belt conveyor was introduced at the colliery. From 1957 onward hydraulic expansion was used in the mining operations. In the near-surface mining operations of the Koenigsgrube colliery, no quarrying could be carried out because of expected damage to the mine . Mountains of backfill were brought underground via the Gustav shaft and in 1954 a rock crushing system was set up on the first level. The backfill material was transported into the old man by means of blow backfill .

The pits were expanded above ground; A second administration building was erected in Hordel and in 1957 brand control was renewed at the Hannibal mine and the heavily war-damaged coke tower was rebuilt as a coal bunker.

On May 1, 1959, the five-day week was introduced; the underground shift output at this time was 1971 kg / man. The annual capacity of the coking plant of 580,000 t was used until 1957. By using the high-fat coal from the Königsgrube, it was possible to increase the discharge of valuable carbon materials.

In the years 1953/54, after the upswing in the first post-war period, sales of coal and coke fell with an increase in stockpile capacities, but this was compensated for in the following years when the labor shortage that then began limited production to around 7,000 tons per day. However, the coal crisis in 1958 led to a decline in coke production. As an adjustment measure , party shifts were set, the workforce was reduced by 400 employees.

From 1964, the Hannibal colliery was also taken on. In 1965 a production of 1.8 million tons was achieved.

Merger of the Krupp collieries to form the Bochum mine and closure (1967–1973)

In the course of the rationalization and reduction of the production quotas, the production of the Kruppzechen was concentrated on the Hannover 2 shaft. A skip conveyor with 24 t containers was installed in the shaft . In 1967 Schacht Hannover 2 took over the entire mining of the mines Hannover, Hannibal, Königsgrube, United Constantin the Great and Mont Cenis, which were combined under the name Bergwerk Bochum . The daytime facilities and the laundry facilities were expanded at the production site.

In 1969 the Kruppzechen were also incorporated into Ruhrkohle AG . As part of the withdrawal of coal production, it was decided in January 1971 to shut down the Bochum mine in 1973. The two Günnigfeld shafts Hannover 3 and 4, which were still used for ventilation , were filled in as early as 1972 . On March 31, 1973, the mine was shut down under the direction of Erich Ricken as the last extraction location in Bochum.

The preservation of the Malakow tower with the shaft structure drawn in from 1873 above the Hanover 3 shaft was still up for discussion; however, the proponents could not enforce the receipt. The headframe was demolished in 1975/76. No structural facilities have been preserved from the Hannover 3/4/6 facility. Only the cobblestone access road still exists.

Originally, the facilities and buildings on the Hannover 1/2/5 facility were to be completely demolished. It is thanks to the preservation of the twin steam hoisting machine from 1878 at shaft 1 that this part of the shaft system and the ventilator building were preserved and restored. In return, the maintenance of the Malakow tower above the Hannibal 2 shaft was abandoned for financial reasons and the tower was demolished in 1978/79.

The preserved part of the colliery is used as a museum .

The Malakow tower above Shaft I and the machine house have been preserved. The mine ventilator building is used as a cafeteria. There are two diffusers next to the building , through which the weather from the pit ventilator was directed into the atmosphere.

The highlights of a visit to the LWL-Industriemuseum are the Malakow Tower, which can be climbed, and the steam engine with traction sheave conveyance from 1893. The conveying machine has been restored and can be started with an electric motor. It is the oldest coal mining steam engine in the Ruhr area that has been preserved at its original location. The LWL industrial museum shows exhibitions in the machine house during the summer opening times.

In 2001, the Regional Association of Westphalia-Lippe (LWL) opened the children's mine “Zeche Knirps” on the museum grounds, the 'shaft' of which is located on the site of the former shaft 5. In teamwork, groups of children learn here how a mine works.

Every two years, the Dampftreffen Steam Festival in the Ruhr area takes place on the colliery site , where road-bound steam vehicles from several European countries were presented under steam.

An ensemble of three privately built settlement houses from the 1890s has been preserved from the LWL industrial museum and will be included in the museum of the Hanover colliery. The houses originally had 131 square meters of living space each and offered space for four to five apartments. One house has been preserved almost in its original condition from 1890/91. The others showed a high degree of damage after the Second World War and were partially changed during the reconstruction in 1949/50. The three buildings have been a registered monument since 1997 and are now owned by the Regional Association of Westphalia-Lippe.
