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 study the law of overlying strata movement in the lower coal seam during the mining process of the near distance coal seams, based on the actual engineering background of the 10-110 face in the papaya mine, the similar materials were used to simulate the mining process of 10 coal from the similar materials The results show that the pressure steps and the displacement characteristics of the overlying strata during the first and the period of the coal seam under the descending mining of the close distance coal group provide the basis for the mining of the coal seam with similar geological conditions Theoretical basis.
