history
The beginnings
In 1781 one was presumption on the pit box Undaunted, the Mining Authority inserted. In the year 1783 another mutation was introduced, this time on the Isabelle-Erbstolln. On March 6, 1790, the right to inherit a tunnel and a length field were awarded . The mine was in operation from 1791, but it was shut down again before 1796. In July 1833, the hereditary tunnel was created, the tunnel mouth hole was 120 meters west of Haus Laer . The following year the tunnel was to the northwest ascended . The final length of the tunnel was at least 1000 meters. After the excavation, dismantling began. In the following time, however, the tunnel was only operated irregularly. Since the deposit was geologically disturbed , the excavated seams were only extracted very irregularly from 1837 onwards . On August 15 of 1837, the mine was shut down and in from 1838 deadlines set. In 1844 the mine was still on time. In 1846 an agreement was made to further dismantle the deposit, the further dismantling now took place through the Dannenbaum Erbstollen. On December 29, 1848, the quarter fields Isabelle A and Isabelle B were awarded as attachments. The authorized person then covered 1.6 km 2 .
The other years
In 1850 the Louise shaft went into operation. A 250 laugh long rail route to Bochum-Crengeldanzer Chaussee was created. In the area of this road there was a coking plant in operation , for which the coal was intended. In the years 1850 and 1851, some Eisenstein fields were awarded to the colliery. After the award, coal iron stone was mined for a while . In 1851, the mining of the coal deposit by the Dannenberg Erbstollen was stopped. The reason for this was the poor reservoir conditions. In 1855, the 250¾ Lachter tunnel was driven in a northerly direction. In the same year the reel shafts Louise I and Louise II were in operation. Louise I had a depth of 15 Lachter and Louise II had a depth of 16¾ Lachter. At this point in time, 14 fat coal seams were available for mining . The thickness of these seams ranged from 16 to 38 inches . At that time, the mine was part of the Bochum jury district . In 1857 operations were resumed above the bottom of the tunnel . The transition to civil engineering was planned for 1860, but this plan was not implemented. In 1861, the northern cross passage on the eastern side of the main fault was driven 37 more holes . The mining took place in seams No. 34, 35, 41, 42, 44 and 46. The mine was part of the Dahlhausen mining district at that time. In 1868 the Isabella colliery was finally shut down and the mine field was acquired by the Dannenbaum colliery. In retrospect, there was consolidation . In the years 1875 and 1879 the Isabella colliery was mentioned again in the documents, but no information was given about any activities.
Promotion and workforce
The first production figures come from the year 1834, 10,836 bushels of hard coal were produced . The following year, production fell to 3444 bushels of hard coal. In 1837 3,053¾ Prussian tons of hard coal were mined. The first workforce dates from 1846, between nine and 19 miners were employed at the colliery. With this workforce, 10,698 bushels of hard coal were mined. In 1855, 40 miners extracted 15,509½ tons of coal from Prussia. In 1860, 35 miners extracted 3,194 tons of hard coal. In 1862, 39 miners extracted 5473 tons of hard coal, the highest extraction in the entire history of the mine. In 1865, 38 miners extracted 4494 tons of hard coal. The last figures come from the year 1868, with seven miners 4026 tons of hard coal were extracted.
Current condition
The effluent from the so-called Isabella cleats mine water , which the work site of the former Opel plant I pass under, for water supplies of moat house Laer.
