Application of microseismic monitoring technology in coal mines

Aiming at the present situation that the ground pressure acts so intensively in Hongtoushan copper mine,a microseismic monitoring system was developed by optimizing the layout of sensors with a three-dimensional geological model developed relevantly to monitor real- time continuously how the ground pressure acts.

The composition and performance of 16-channel microseismic monitoring system established recently in the mine and the monitoring area are introduced in detail.

Base on the micro-seismic monitoring technology,the setting-up of the rockburst control system in deep level mining can improve the safety of mines with rockburst proneness or rockburst hazard.

In order to better understand the regularities of rockburst occurrence,Dongguashan Copper Mine has installed an ISSI seismic monitoring system,which can make a real-time monitoring of rock mass respond to mining.

Application of ground pressure disasters micro-seismic monitoring technique in deep level mining

According to the actual situation during mining,digitalized 24-channel micro-seismic monitoring system was established,which has functions of seismology quantitative analysis and visualization interpretation.

Based on the micro-seismic monitoring results and in order to present the dynamical process of strata fracturing,the method of synthesizing the micro-seismic monitoring results into mining maps is researched and its application introduced.

In this paper,the theories,techniques,methodologies,and results of monitoring primary fractures connecting to the injection well in Anpeng Alkali Mine are presented, which combines micro-seismic monitoring with leveling survey techniques.

Independent micro-seismic monitoring systems called MEMS had been developed in this paper.
