摘　　要：为研究近距离煤层群开采过程中下煤层的覆岩运移规律,基于木瓜矿10-110首采工作面的实际工程背景,采用相似材料对该矿10煤开采过程进行模拟,从相似材料运移形态、移近量等方面对覆岩运移规律进行了分析,研究表明:近距离煤层群下行开采下煤层初次和周期来压步距、覆岩位移特征,为相似地质条件煤层的开采提供理论依据.In order to research the overlying strata movement rule of lower layer in mining the close coal seams, based on the work face 10-110 of MU-Gua mine, analogue material was used in simulating the mining process of the 10 coal seam, and analyzing overlying strata movement rule through the pattern and displacement of analogue material. This study obtained the first time and periodical cave pace and strata displacement characteristic, which provides theoretical base for mining of coal-seam with similar geological condition.
