微地震监测技术对塔山煤矿围岩运动规律的研究
|
摘要
本文探讨了采用高精度微地震监测技术,对大同塔山煤矿特厚煤层综放工作面开采过程中的围岩活动规律、煤岩层破裂和相关的应力场变化进行监测与分析,对回采过程中超前支承压力分布变化规律进行研究,并为推进特厚煤层放顶煤开采理论及技术的发展提供科学依据.
The author,by applying high-precision micro earthquake monitoring techniques,monitors and analyzes the law of surrounding rock activity,coal seam rupture,and stress field changes in mining ultra-thick seams in Tashan Colliery,and studies the stress distribution of the pilot support in mining,thus provides scientific basis for the development of caving mining theories and technology.
