摘　　要：基于冀中能源股份有限公司东庞矿S2704工作面采高大、开采条件复杂等的情况,建立了工作面顶板的力学分析模型,并对工作面开采过程中的矿压显现规律进行了实测分析,结果表明:双向倾斜工作面来压具有明显的周期性,随着工作面的推进,垂直应力分布主要表现为下部大,中部次之,上部小的特征,揭示了特定条件下的矿压显现规律。Based on Dongpang Mine of Jizhong Energy Corporation,S2704 working face with large mining height, complicated mining conditions, the roof of the mechanics analysis model was constructed, the mine pressure appearance law in the process of working face mining was measured and analyzed, the result showed that two-way inclined working face pressure had obvious periodicity, with the working face advance, the vertical stress distribution with appearance of the lower big, then middle, upper small, which revealed the regularity of mine pressure appearance under certain conditions.
