摘要
从地震前后发生的应力集中、应力释放、地震活动(冲击地压)3个角度,分析了开采空间瓦斯涌出量变化的情况,从引发机理角度进行了详细分析,得出了地震活动可能引起煤矿瓦斯事故的结论.地震活动与煤矿瓦斯事故之间的关系,对煤矿生产基础理论和地震中短期预报可能产生深远影响.
Studied the changes of gas releasing during the course of stress increasing, decreasing and stratum quivering when earthquake happens. Finally got the result that there exists the possibility that earthquake causes some of the gas accidents in coalmine. The relation between earthquake and gas accidents may have a great effect on traditional coalmine production elements theory and earthquake near-predicting.
