Feasibility Study on Microseismic Monitoring of Stability in Yanqianshan Iron Mine
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.
