摘要

为了研究同煤塔山特厚煤层综放面围岩运动的规律,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。
In order to probe the movement regularity of the surrounding strata around the top coal caving longwall faces in Tashan extra-thick coal seams the principle is determined for the arrangement of sections to be monitored in line with the actual conditions of the top coal caving longwall faces and the technical requirements for micro-seismic monitoring with high accuracy.On analyzing the main factors affecting the accuracy of monitoring positioning and a comparison of data gathered,the surrounding strata movement parameters are obtained for the top coal caving longwall faces in extra thick coal seams in Tashan Coal Mine.
