中文摘要：

采动影响下厚黄土层沉陷规律研究对指导矿区进行＂三下＂压煤开采设计和完善开采沉陷预计理论等工作具有重要意义。为得到采动影响下厚黄土层沉陷规律,以阳湾沟煤矿6204工作面采动影响下上覆厚黄土层为研究对象,采用钻孔电视探测和多点位移传感器实时监测等方法,探测黄土层内裂隙分布情况以及黄土层内部采动沉陷规律。结果表明：厚黄土层完整性好,内部无明显裂隙;厚黄土层近于整体下沉,且其下沉值近似等于地表下沉值,黄土层与地表同步运动。

英文摘要：

It is important for coal pillar mining under buildings,railways and water-bodies and perfecting coal mining subsidence prediction theory to study mining-induced subsidence law of thick loess layer. Based on 6204 working face of Yangwangou Coal Mine,borehole TV detection equipment and real-time monitoring equipment for measure points subsidence value were used respectively,to detect inner mining induced fracture and reveal subsidence law of thick loess layer. It shows that thick loess layer has good integrity,and has no inner mining-induced fracture. Furthermore,it is obtained that thick loess subsidence as a whole,whose subsidence value approximately equal to surface subsidence value,and keeps in step with the surface.
