摘　　要：为了研究矿震对地面建筑物破坏的影响以及矿震震源所能影响到的范围,本文以老虎台矿83003综放工作面为研究对象,综合应用地震学、地球物理学、统计学、地质动力区划等方法研究矿震对地面建筑物破坏程度的影响及矿震震源影响范围。以83003综放工作面发生过的几次较大矿震为对象进行分析,应用经验公式计算出不同震级、不同烈度的矿震所对应的震中距,为矿震对地面建筑物破坏程度及震源影响范围给出了参考。根据老虎台矿微震监测系统记录到的微震震级和抚顺地震台提供的地震里氏震级,应用数学方法拟合了微震震级与地震里氏震级之间的转换关系。通过现场调查证明了这种方法来预测矿震对地面的影响是可行的,对研究矿震对地面造成的影响有一定的科学参考价值。In order to study the mine earthquake influence on the ground buildings destruction and the mine earthquake seismic source can influence range,in this paper takes 83003 fully mechanized caving face of Laohutai coal mine as the research object,comprehensive application seismology,geophysics,statistics,geo-dynamic division,et al methods to study the mine earthquake influence on the ground buildings destruction degree and the mine earthquake seismic source can influence range.Based on 83003 fully mechanized caving face happened several larger mine earthquake to analysis,applying empirical formula calculated different magnitude,different intensity mine earthquake corresponding to epicentral distance,providing reference to mine earthquake influence on the ground buildings destruction and the mine earthquake seismic source can influence range.According to the Laohutai coal mine micro-seism monitoring system recorded micro-seismic magnitude and Fushun seismic station provide earthquake Richter scale,applying mathematical method are fitted the conversion relationship of micro-seismic and Richter scale.By field investigation this method has been proved to predict the mine earthquake influence on ground is feasible,for study on mine earthquake influence on ground has certain scientific reference value.
