该文针对鄂尔多斯地区典型近浅埋煤层的实际地质情况，在“关键层”理论的基础上，对近浅埋煤层大采高工作面矿压规律及采场上覆岩层运动特征进行了研究。研究发现：主、亚关键层在不同的破断距和破断形式的相互作用直接导致采场周期来压步距和来压强度均呈现非均匀性周期变化，并通过关键层破断对采场来压影响分级和现场实测等方法对理论分析结果进行了验证。论文对近浅埋煤层长壁开采的特殊来压规律进行合理解释，为现场工作面安全生产提供理论依据。

Aiming at the real geological conditions of the typical near shallow coal seam in Ordos region, the mining’s pressure behavior and the motion characteristic of its overlying rock strata in the near shallow coal seam with high mining height is studied with the method of key rock strata theory.This study shows that the interactions between the two key-stratas`weighting steps and fracture forms lead directly to the periodic caving span and weighting intensity working face have a periodic change. And the analyzed theory result was veriifed by grade the Factors that affect pressure sizing and ifeld measurement methods. The special strata laws of long-wall mining in near shallow seam were explained, which provides a theoretical basis for safety production at scene working face.
