Abstract
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.
