摘要
以经坊煤矿3-807工作面为研究背景,采用两种方案对工作面支架选型进行核验,支架工作阻力宜大于4796kN,矿山现有的ZF5800—16/30型液压支架可以满足支护要求,同时对综放工作面支护方式、顶板控制进行了研究。
Taking 3-807 working face of Jingfang coal mine as research background, two schemes are adopted to verify the selection of support types in working face, the working resistance of support should be greater than 4 796 kN, the ZF5800-16/30 hydraulic support in mines can meet the supporting demand, at the same time, the support mode and roof control of fully mechanized caving face are studied.
