摘要
综合应用了相似模拟实验与理论分析的方法,对45°特厚煤层开采过程中采场结构失稳特征及其致灾理论进行了分析,对类似条件煤层的安全开采具有一定的指导意义。
By using the method of similar simulation experiment and theoretical analysis, the characteristics of stope structural instability and its disaster-causing theory in the mining process of 45° extra-thick seam are analyzed,which has certain guiding significance for the safe mining of coal seams under similar conditions.
