摘要/Abstract

摘要： 矿震的发生受多个因素耦合控制。为研究不同诱因条件下矿震分布对冲击地压的影响,基于反演计算推导,得到走时与临界距离公式,并借助微震检测手段,结合现场开采实际,从关键层运动、回采速度的稳定性的角度分析矿震发生机制与分布。研究发现,矿震的发生可分为若干个活动周期,强矿震的发生均处在矿震活动周期内峰值位置;关键层处微震信号最为集中,信号首先于基本顶处集聚,后逐渐向关键层扩展,后再次于基本顶处集中显现;回采速度的变化能够引起突发性顶板垮落,加快回采速度,会造成工作面前方出现高应力集中区,且高应力集中区随工作面的推进逐步向工作面靠近;日进尺突然增加使里氏震级与频次的曲线出现较为强烈的波动。

Abstract: The occurrence of mine earthquake is controlled by many factors. In order to study the effect of mine earthquake distribution on rock burst under different conditions of incentives, the travel time formula and the critical distance formula were got by means of inversion calculation,and rock burst mechanism and distribution were analyzed from aspects of key stratum movement and the stability of the mining speed on the basis of data collected during seismic detection. Research results show that, the occurrence of mine earthquake can be divided into a number of activity periods,that the microseismic signals first gather in the main roof, then spread to the key strata, finally appeare in the main roof, that changes in mining speed can cause sudden roof caving,and speeding up mining makes a high stress concentration area appear in front of working face, and the distance between the two becomes shorter and shorter as the working face advances,and that a sudden increase in daily footage has s singnificant effect on both the earthquake magnitude and the frequency.

Key words: back calculation, rockburst, microseism, motion period, key strata, mining speed
