【摘要】 文章归纳出灰山港 煤炭坝矿震具频度低、强度小、烈度高 ;系孤立型及主震 -余震型 ;地震活动无明显的规律性可循和无前兆的突发性等特征 ,进而分析了地震构造环境、地震孕育及发生的动力因子。认为该区处在多个活动块体交汇及活动断裂夹持区域 ,是构造应力集聚较高地区 ,加之 ,区内存在地壳内花岗岩层和玄武岩层上涌的热能附加应力和人类采掘煤矿工程活动引起的诱发地震的功能 ,以致灰山港 煤炭坝地区时有矿震活动更多还原

【Abstract】 The earthquakes occurring in Huishangang-Meitanba area are characterized by low frequency and intensity but high magnitude, isolated type or main shock-after shock type. Since there is no regulation to follow and no premonitory symptoms to be observed,seismotectonic environment and dynamic factors have been analyzed.Study result shows that the area locates in a high tectonic stress zone where active blocks meet active faults,further more,the up gushing geothermal energy from the crust consisting of granite and basalt,and mining engineering activities also play a role in the seismotic activities of Huishangang-Meitanba area.更多还原
