摘要
为了解决薄煤层回采巷道支护问题,针对某矿薄煤层开采的实际情况,通过理论分析,确定了回采巷道净高、净宽的合理尺寸,并计算得出围岩破坏范围以及巷道锚杆支护的具体参数,为工作面的安全高效开采提供保障。
In order to solve the support problem of thin coal seam mining roadway, according to the actual situation of thin coal seam mining in a mine, through theoretical analysis, the reasonable size of the net height and net width of the mining roadway is determined, and the damage range of the surrounding rock and the concrete parameters of bolt support are calculated, which provides guarantee for safe and efficient mining of the working face.
