In Shizhuyuan poly-metallic mine,because of the intensive existence of a large n umber of mined-out areas,the phenomenon of pressure appeared is serious in minin g process,the safety in mining production was seriously threatened.Therefore,coo peration with Changsha Institute of Mining Research,based on the optimization of mining technology,the mine has established several conventional ground pressure monitoring system.By introducing pressure monitoring devices from ESG company of Canada,mine has established a all-digital type multi-channel micro-seismic mon itoring system which is one with most channels in China’s mines.This paper descr ibes the system’s implementation,optimization and field applications,discusses the advantages and effects of multi-channel micro-seismic monitoring technology in the prevention and control of mine pressure disasters.
