摘  要:郑煤集团公司超化煤矿改变三软特厚煤层传统的架棚被动支护方式,采用锚梁网主动支护,先锚杆+钢筋梯子梁+钢网支护、后打锚索结构补强的支护方法。实践证明,煤巷锚网梁主动支护显著提高了巷道支护效果,降低了工人劳动强度。同时能够与综采工作面配套减少替棚工序,降低掘进成本,保证了采煤工作面的安全、快速推进。The traditional passive shield supporting in Three Soft thick coal seam was changed in Chaohua Coal Mine of Zhengzhou Coal Industry( Group) Co.,Ltd.,the active supporting method,roof bolting with bar and wire mesh,was carried out in the coal mine. Firstly,using bolt + bar ladder beam + steel net; secondly,anchor cable was used for structure reinforcement. The practice proved that,the active supporting of roof bolting with bar and wire mesh in coal roadway has effectively improved the effect of roadway supporting,and reduced the labor intensity of the workers. At the same time,it can reduce the working procedure and the driving cost,and ensure the safety of the coal mining face.
