摘要
针对王家岭煤矿在首个综放大断面沿空掘巷巷道支护中出现的问题,进行了详细的矿压观测,并分析了原有支护存在的问题,揭示了综放大断面沿空掘巷矿压显现不对称性的原因,进而提出了不对称支护的支护方案,并在20103区段运输平巷成功进行了工业性试验。
In order to solve support problems in the first roadway driving along next goaf in longwall top coal mining of Wangjialing coal mine, mine pressure observation has been done and the existing problems of original support scheme is analyzed. It reveals the reasons that why it is asymmetric in mine pressure in that case. A new asymmetric support design is put forward and applied in haulage gateway 20103.
