摘要
为探究工作面转采诱发的矿震规律,以山寨煤矿1104工作面实际工程地质为研究背景,采用微震监测技术为研究手段,从矿震的能量、频次与时间的关系和矿震的时空演化两方面分析了采动诱发的矿震规律。结果表明:当工作面推进至转交区域时,日震动能量和频次波动较大,整体应力值较高,冲击危险性急剧增加。
In order to explore the regularity of mining-induced tremor,taking the actual engineering geology of 1104 working face of Shanzhai Coal Mine as the research background and using MS monitoring technology as the research means,the regularity of mining-induced tremor is analyzed from the aspects of energy,frequency and time relationship and time-space evolution of mining-induced tremor.The energy and frequency of daily vibration fluctuate greatly when the plane is pushed to the transfer area,and the overall stress is worthwhile,and the impact risk increases sharply.
