增子坊煤矿8115工作面过U型棚支护工艺的实践应用
|
摘要
以增子坊煤矿8115工作面通过U型棚区域为研究对象,对2115运输顺槽、5115回风顺槽的超前支护与端头支护进行设计,针对工作面过顶板松软破碎区时工作面推进困难的问题,提出瑞米加固工艺,实践表明,该工艺能有效缓解巷道顶板破碎情况,实现工作面安全过U型棚区域的目的。
The 8115 working face of Zengzifang Coal Mine was passed through the U-shaped shed area as the research object. The advanced support and end support of 2115 transport sluice and 5115 return air sluice were designed. When the working face is difficult to advance, the remy reinforcement process is proposed. The practice shows that the process can effectively alleviate the broken roof of the roadway and achieve the purpose of safely working the U-shaped shed area.
