摘要
为了研究同煤集团塔山煤矿特厚煤层综放面围岩运动的规律、科学地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,按高精度微震监测技术的要求,确定了测区布置的原则,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比对,初步得出了塔山煤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 of Datong coal mine group to study the movement law of the surrounding rock mass in order to provide a scientific basis for the coal mining design and the mining pressure control. According to the practical situation of the fully mechanized top - coal caving face, the arrangement principles of survey area is determined and data is collected and anylized on the basis of the requirements of high - precision microseismic monitoring technique. The movement parameters of the surrounding rock mass on the coal caving face.
