【摘要】 以冬瓜山微震监测的数据为基础,运用统计学和线性拟合方法研究矿震事件的时空分布规律。结果表明,矿震事件的发生与开采活动相对应,小震级事件比大震级事件的分形特征要明显,前者主要受开采条件的影响,而后者主要受自然地震、地质构造等影响。更多还原

【Abstract】 Based on the data of micro-seismic system of Dongguashan mine,the time-space distribution law of seimic events is investigated by statistic and linearization methods.The results show that the seismic events are related to the exploiting activity,and the fractal feature of the small events is more obvious than that the big events,the former are mainly affected by exploiting activity,and the later are mainly by natural earthquake and geologic conformation.更多还原
