Loosening (mining)
In mining, loosening or dissolving was the term used to describe the discharge of pit water or the weathering from the pit field . In early mining, the term “loosening” meant “helping” a building with shafts and tunnels.
application
In early tunnel mining , it was often not possible for a single mine to drain its own pit water. The solution, i.e. the drainage, of this water was then taken over by other mines or specially built hereditary tunnels . Most of the time, these tunnels were also used to divert the weather . The development of a deposit was also described as a solution.
Today, the designated Bergmann as dissolving during the sedimentation caused the rock interfaces between rock layers or between the strata and of the deposit. Due to this loosening can, particularly in an inclined storage , so-called by the penetration of moisture lubricating packing form. In addition, this can lead to the rock layers shifting in the direction of the dipping . In potash and salt mining is plate-shaped referred to separating salt rock in the ridge area as a solver .
