Maintaining the mine workings will also require significant costs to repair them both before and after they are introduced into production, especially in the zone of influence of the mining operations. Maintaining and increasing the volume of underground coal mining is only possible with a highly efficient technology for conducting and maintaining preparatory workings. The purpose of the study was to assess the parameters for controlling the stability of the contours of mine workings secured by anchor support to create a technology for intensive and safe conduct of mine workings based on the identified patterns of behavior of the adjacent rock masses. The idea of the approach is to use the anthropogenic stress-strain state to develop an effective technology for securing the contour rock massif. The mechanism of rock deformation, shear and collapse in a structurally disturbed heterogeneous rock massif is studied to assess the state of the rock massif around mine workings. Technological prerequisites for anchoring the marginal soil rocks, taking into account the state of the rock mass around the excavation, are developed and the parameters of anchor support operation in mines to secure the rods in excavations to ensure the safety of mining operations are determined.
