Fastening of Near-contour Soil Rocks, Taking into Account the State of the Mountain Range Around the Working

The maintenance of excavation workings will also require significant repair costs both before and after they are put into operation, especially in the zone of influence of stoping operations. Maintaining and increasing the volume of underground coal mining is possible only if there is a highly efficient technology for conducting and maintaining development workings. The purpose of the research was to evaluate the stability control parameters of the contours of mine workings, fixed with anchor bolting, in order to create a technology for intensive and safe excavation of excavation workings based on the identified patterns of behavior of adjacent rock masses. The idea of the approach is to use the technogenic stress-strain state to develop an effective technology for fastening the near-contour rock mass. The mechanism of deformation, displacement and collapse of rocks in a structurally disturbed heterogeneous rock mass was studied to assess the state of the rock mass around mine workings. A technology for fastening near-contour soil rocks has been developed, taking into account the state of the rock mass around the working, and the parameters for the operation of rock bolts in mines for fixing rods in workings in order to ensure the safety of mining operations in the mines of the Karaganda coal basin have been determined.
