The Unna colliery is a former hard coal mine in Unna-Mühlhausen . The mine was also known as the Mühlhausen I colliery . The mine shaft was popularly known as the Schmorbach shaft.

history

The beginnings

In 1855 that was the innkeeper Nottebohm Grubenfeld Mulhouse I awarded . The award ceremony, which took place on May 16, was for the mining of hard coal and iron ore . On June 7 of 1860 which were square boxes Uelzen I, II and Uelzen Mulhouse I to Mulhouse I consolidated . The Uelzen I square was awarded on February 22nd, 1859, and the Uelzen II square was awarded on January 2nd, 1856. Both fields were lent for the mining of iron ore. On May 14, 1870, the Geviertfeld Korten I consolidated to Mühlhausen I. Korten I was awarded on December 15, 1866 for the mining of iron ore.

Construction of the mine

In 1920, the sinking work for the Mühlhausen I shaft began. The bay was south of the Werlerstraße, today's federal highway 1 , stated . The shaft was sunk in a field east of the former "Onkel Albrecht" inn. The owner of this field was the farmer Ostemann. Strong water ingress occurred at a depth of 80 meters. The water leaks were so strong that the shaft to ten feet below the grassy bank absoff and gesümpft be had. After the shaft was swamped, the sinking work continued. The first level was set at a depth of 120 meters (-5 m above sea level ). Then the alignment of the mine field was started on the first level . Two cross passages were driven , one to the south and one to the north. In addition, two straightening sections , one in the east and one in the west, were excavated. At that time, the rightful owner covered an area of 1.03 km ² . The Neuer Hellweg field was acquired to enlarge the mine field. This field had an area of 3.4 km ² . The entire right now encompassed an area of 42.1 normal fields . In 1922, the second level was added from a sloping stretch . At a depth of 162 meters (- 47 m above sea level ), the second level was driven as the first underground level. This year, 85 miners were employed at the mine.

Operation until decommissioning

Mining began in 1923. At this point in time, the construction site had an extension of 7000 meters, striking and 2700 meters across. This year 9,161 tons of hard coal were mined, the workforce was 68 employees. In the following year, 4225 tons of hard coal were initially mined. On July 1st of the same year the Unna colliery was shut down. The reasons for the closure of the mine were initially the poor geological conditions of the deposit and the inadequate deposits. The mine was built in a hollow with no significant amount of coal. Then there was the lack of money for the owners. After the closure, the Mühlhausen I shaft was backfilled and the daytime facilities were demolished.
