The Johanna colliery is a former hard coal mine in Durchholz -Hammertal. The colliery was also known as the Johanna colliery in Herbeder Holz . The mine belonged to the Märkisches Bergamtsiertel and there to the jury area Hardenstein .

Mining history

The first suspicion was lodged with the mining authority in 1779 . In the year 1785 a new test was made, and a survey was carried out that year . The measurement was carried out from the first production shaft in an easterly and westerly direction. In the following year, one tunnel each to the west and one to the east were excavated from the Pleßbachtal . The approached seams had a thickness of 59 inches with a mountain strip of 10 to 17 inches. The height of the coal pillar was 30 laughs . The existing seams were coal seams . The mine was in operation around 1820. In 1827 a length field was awarded . The award was made for the mining in the Johanna seam. In 1842 the mine was demonstrably in operation. On March 24th and April 9th, 1847, the Geviertfeld Johanna was awarded. The quarter field was in Herbeder Holz. In 1855, six miners extracted 93½ tons of hard coal from Prussia . Starting in the 2nd quarter of 1858, the Johanna colliery was laid in time limits . From 1875 to 1910 the owner belonged to the Blankenburg colliery . In 1933 a subfield consolidated into the Elisabethenglück colliery .
