摘要
文章介绍了眼前山铁矿工程背景及回采过程中面临的地压问题,结合多通道微震监测技术特点,制定了覆盖采区的48通道微震监测系统技术方案。采用D值最优设计理论,对传感器进行了优化布置,确定的采区微震监测技术方案可实现回采过程中采区稳定性实时、在线和全方位立体监测,为采区安全回采提供技术支撑。
In this paper,the engineering background of Yanqianshan Iron Mine and the ground pressure problems in the mining process are introduced.Combined with the characteristics of multi-channel microseismic monitoring technology,the 48-channel microseismic monitoring system covering the mining area is developed.Based on the D-value optimal design theory,the sensors are optimized,and the determined microseismic monitoring technology scheme can realize the real-time,online and all-round three-dimensional monitoring of the stability of the mining area during the mining process,and provide technical support for the safe mining area.
