【摘要】 利用１９８８～１９９５年６月间抚顺老虎台煤矿１００个矿震记录的５３４个Ｐ波初动方向数据和抚顺及周围地区１２０个天然地震记录的５２６个Ｐ波初动方向数据，用格点尝试法分别计算出它们的综合断层面解的Ｐ、Ｂ、Ｔ轴并对其进行了对比分析，初步认为较大矿震（ＭＬ≥１．８）反映出的应力场状况与天然地震所反映的地壳构造应力场有一定相关性。更多还原

【Abstract】 On the basis of wave first motion data of 100 mine earthquakes which cover Fushun region in Liaoning Province during 1988～1995,we have deduced the mean P、B and T axis of the compsite fault plane solutions using the grid testing method.From the comparison and analysis of the results,an initial conclusion had been reached that there is a quite good correlation between the stress field of the relatively large mine earthquakes and the crust structure stress field suggested by natural earthquakes. 更多还原
