PROSPECTIVE METHODS OF ASSESSMENT AND CONTROL OF THE GEOMECHANICAL STATE OF ROCK MASSES

Abstract

Safety of mining operations largely depends on the study of the stress state of the rock mass, their physical and mechanical properties and structural features, and it is largely determined by the timeliness and accuracy of the parameters of geomechanical processes in the justification of technological solutions. In order to prevent accidents due to dynamic aspects of rock pressure, sudden caving of the mined-out space, landslide and other hazardous geological processes, it is necessary to provide information on the state of the rock mass and forecast on the development of geomechanical processes. By now to solve a wide range of problems in the planning and execution of mining operations in complex mining and geological and bump-hazardous conditions, the extensive experience has been accumulated in the creation and application of methods and technical means for studying, evaluating and monitoring the geomechanical state of rock masses. The paper summarizes and systematizes the data on approaches, methods and technical means of assessment and control of bump hazard and experience of their application for forecasting and prevention of hazardous geodynamic phenomena in the underground mining.
