Abstract

Increasing the depth of mining operations at Charmitan vein Deposit complicates the geomechanical situation, which is expressed in an increase in the number of col- lapses of host rocks in the treatment space, where the workers of the treatment unit are located. The only way to normalize the geomechanical environment is to implement development systems with a bookmark of the developed space. In connection with the above, full-scale methods of measuring the stress state by the finite element method, modeling of the geomechanical situation were carried out. In the course of research, the parameters of force fields in natural and technogenic-modified areas of the field were evaluated and the safe design parameters of development systems were justified.
