摘要
吴四圪堵矿井6101工作面开采煤层属于特厚煤层,为研究在此工作面采用综放开采时顶煤的冒放性以及顶板活动规律,建立了比例为1:100的相似模型,并模拟工作面实际推进情况,通过观察与测量得到顶煤及煤层顶板运动的一些规律,得出工作面采出率能达到80%左右,这些都可以为实际的生产工作提供指导。
6101 working face ofWu Si Ge Du wall mining in coal seam belongs to the ultra thick coal seam, as the research on the working face in roof caving in using fully mechanized top-coal and roof movement rule, proportion of h100 similar model is established, and the situa- tion of propulsion simulation working face, through the observation and measurement of get some laws of top-coal and roof of coal seam move- ment, draw a face extraction rate can reach 80%, which can provide guidance for the actual production work.
