Abstract
Summary
The damage of rock mass due to mining as a means of minerals extraction is mostly connected primarily with subsurface voids whose volume may be as large as tens of millions m3. It causes rock mass deformation and therefore the soil surface. In order to prevent dangerous emergency situations (DESs) of geological nature are used different methods.
The work proposed is aimed at resolving specific problems concerned with the current issue mentioned. Besides, among other geological and mining spacial factors, the authors study the capacity margin factor and prove that its role is dominant in surface settling. To illustrate the problem and solution, the reference is made to Kalush-Holyn potassium salt field. The practical implication of the model developed is the possibility to assess the level of surface deformation using the capacity margins factor of pillars for mining potassium salt fields.
