The Freudenberg colliery in Schüren is a former hard coal mine . Despite the more than 70 years of mining history, little is reported about the mine.
Mining history
In 1754 the mine was already on time . On January 5, 1755, the mine was still within deadlines. At this point in time, the mine tunnel had been driven to a geological fault . On March 14th, 1776, the idea of a tunnel on the Emscher was introduced. In the tunnel was a seam with a thickness of 25 inches available. Of this, only 12 inches was coal , the remaining 13 inches was fire slate . Following the presumption of the seam was first in Verhieb taken, but due to poor coal mining was not rewarding. In 1788 a length field was measured . In the months of May to August of 1808, clearing work was carried out in the tunnel . From September of the same year, the mine was out of order. On July 22nd, 1811, the Mutern was awarded the supposed pit field based on a judgment of the mountain court in Wetter . In the mine field there were three seams that had been driven over with the tunnel of the Freudenberg colliery. In 1826 belonged Berechtsame already the colliery Assumption & St. Martin Nr. 4, .
