The results of rock burst prediction on the sokolovskaya underground mining by the acoustic emission method

Authors: Mengel’ D.А.

The relevance of research. When developing underground mining, there is a risk of dynamic phenomenon of high rock pressure — rock burst. The local instrumental forecast of shock hazard by acoustic emission with the GS-01 device allows you to quickly identify high-tension zones during underground mining. The Research aim: generalization of the accumulated data of instrumental measurements of acoustic emission parameters throughout the Sokolovskaya mine; zoning of rock burst hazard in the deposit; use of zoning of rock burst hazard results for mining planning in terms of changing the principles and regulations for designing traces of mine workings in potentially impact hazardous areas; improving the methodology of instrumental forecasting of shock hazard by the acoustic emission method. Methods of research: analysis of the accumulated data of instrumental measurements of acoustic emission parameters during mining; theoretical studies (identifying patterns of changes in acoustic emission taking into account the influence of mining, the configuration of the excavation, etc.); measurement in situ (measurement of acoustic emission parameters when changing parameters underground working). Results of research: implementation of preventive measures (the so-called “relaxation” of the rock) to reduce the rock burst risk in hazard zones during mining; implementation of research results in normative and technical documentation.

Keywords: rock burst risk, rock mass, geomechanical monitoring, stress-stain state, acoustic emission, rock pressure, rock burst, safety of processes, signs of rock burst risk.
