摘要
在研究了14202工作面侧向支承应力数据的基础上,分析了麻家梁煤矿特厚煤层综放开采支承应力沿倾向的动态分布演化规律和倾向支承应力的波动范围,确定了减小临空巷强矿压显现的最根本的手段是采用工作面跳采。
Based on the analysis of the lateral abutment pressures data of the 14202 working face, the evolutionary law and the affecting range of the abutment pressures of the Majialiang coal mine are revealed. The most fundamental means of reducing the stress and development of the roadway is to use the skip-mining face.
