微地震技术在特厚煤层开采中的应用
|
摘要
为研究大同煤矿集团公司塔山矿特厚煤层综放面围岩运动规律,科学进行开采设计,并为矿山压力控制提供科学依据,根据综采放顶煤工作面的实际情况,按高精度微地震监测技术的要求,确定测区布置的原则,分析了影响监测定位精度的主要因素,对采集数据进行了研究分析、对比,初步得出了塔山矿特厚煤层综放工作面围岩运动参数。
Microseismic monitoring technology is used on fully mechanized coal caving face of extra-thick coal seams in Tashan coal mine,Datong coal mine group to study the movement law of the surrounding rock mass in order to provide a scientific basis for the coal minig design and the mining pressure control.According to the practical situation of long wall mining with caving coalface and the request of the high precision micro earthquake monitoring technology,the author determines the principle of surrey area's arrangement,analyzes the influence of monitoring positioning accuracy,and studies the collected data.At last we gets the motion parameters of surrounding rock mass,coalface in thick coal seam of Tashan coal mining.
