Influence of tectonic disturbances on the parameters of excavation support with rock anchor

[摘要] The mechanism of deformation, movement and rockfalls in structurally disturbed nonuniform rock mass using analytical modeling operation for assessment of the strain-stress state (SSS) of the rock mass around mining has been investigated. The SSS research of the rock masses by means of the ANSYS program of the excavation in the "Saransk" mine of coal mining JSC "ArselorMittal Temirtau" in the Karaganda coal basin has been conducted. The parameters of the exploitation of the anchor support on the mines for fixing the rock bolts in the workings to ensure the safety of mining operations in the areas of geological disturbances have been determined.
