A rational approach to the management of underground mining in complex hydrogeological and geomechanical conditions based on a risk assessment

Abstract

The problems that arise during the combined development of vertical and subvertical ore bodies under complex hydrogeological and geomechanical conditions are considered, and their influence on the safety of mining operations is analyzed. In the course of the research, using the example of kimberlite deposits in Yakutia, new mechanisms were identified and spatial patterns were established for the development of processes of deformation, displacement and destruction of ore and rock masses during preparatory excavations and treatment works near surface and underground water bodies, including high-pressure ones. The mechanisms of complex accounting of the structural state of the massif, preliminary technogenic impact, the effect of complicating mining and geological and hydrogeological factors in substantiating the parameters of hazardous zones and barrier pillars are proposed. Risk assessment method based on hazard identification, a qualitative and quantitative analysis of the likelihood of an emergency considering the severity of the consequences when conducting mining in hazardous areas is presented. The application of the method in combination with the timely adjustment of technological processes provides a rational integrated use of geo-resources in the framework of sustainable development of mining system. The experience of training young personnel for scientific research institutes is described. Starting with university education and ending with their participation in real design work.
