柿竹园多通道微震监测系统的建立及其应用

Implementation and Application of Multi-Chiannel Microseismic Monitoring System in Shizhuyuan Mine

在柿竹园多金属矿床,由于大量集中采空区群的存在,采矿生产过程中地压现象显现严重,安全生产受到严重威胁。为此,公司与长沙矿山研究院合作,在优化采矿工艺的基础上,先后建立了多种常规地压监测系统,并从加拿大ESG公司引进地压监测设备,于2008年11月建立了国内矿山最大通道的全数字型微震监测系统。详细介绍了微震监测系统的建立、优化及其现场应用情况,论述了多通道微震监测技术在矿山地压灾害防治方面所展示的优势和效果。

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.
