摘要
通过分析抚顺老虎台矿地质构造、开采、气象、矿震记录等资料 ,总结出了老虎台矿矿山地震活动的一些基本规律。研究结果表明 ,开采深度、强度、采煤方法等是影响矿震时序分布的主要因素 ,矿震在一年中的分布与同期降雨量成负相关 ,在现行开采条件下 ,矿震规模有增大的趋势 。
In this paper, based on the analysis of geological tectonics, mining status, meteorologic data and mine tremor records in Laohutai coal mine, Fushun City, China, some fundamental law regarding mine tremors' activity in Laohutai coal mine is summarized. The results show that the time distribution of mine tremor is mostly affected by mining status, such as method, depth and intensity. The results also show that the frequency distribution of mine tremors in one year has negative correlation with the rainfall. Under the current exploitation condition, the mine tremors' activity shows an enhancemental tendency. The location of mine tremors is mainly controlled by the large faults and structures in the mining area.
