针对神东矿区各煤矿不同地质条件、上覆岩层组成情况及煤层赋存情况，运用RFPA2D数值模拟软件，分析了不同上覆岩层结构（松散层厚度、基岩厚度、直接顶厚度）对短壁单翼旺采工作面岩层运动和矿山压力的影响规律，为神东单翼旺采工作面安全高效开采提供了理论依据。
針對神東礦區各煤礦不同地質條件、上覆巖層組成情況及煤層賦存情況，運用RFPA2D數值模擬軟件，分析瞭不同上覆巖層結構（鬆散層厚度、基巖厚度、直接頂厚度）對短壁單翼旺採工作麵巖層運動和礦山壓力的影響規律，為神東單翼旺採工作麵安全高效開採提供瞭理論依據。

In the light of the different geological conditions, the composition of overlying strata and the occurrence of coal seam in all coal mines in Shendong mining area, this paper analyzes the influencing rules of different structures of overlying strata (the thickness of the loose bed, the thickness of the bedrock, and the thickness of the immediate roof) on rock strata movement and mining pressure of short-wall single-wing prosperous mining face, which provides the theoretical basis for the the safe and efficient exploitation of Shendong’s single-wing prosperous mining face.
