针对煤矿井下高抽巷施工综掘机钻孔技术在操作过程中因巷道距离长、钻孔技术难度大,导致综掘机工作环境不佳、工作量大的问题,提出一种煤炭领域新型全断面掘进技术,即泥水平衡顶管施工法,并简要介绍了泥水平衡顶管施工法操作流程及在岩巷采用泥浆输送系统的可行性分析,对泥浆渣石输送管道进行了设计计算并验证。
Aiming at the problem that the drilling technology of the fully-mechanized excavating machine in the coal tunnel with a high level of roadway extraction in the coal mine due to the long distance of the roadway and the difficulty of the drilling technology, the working environment of the fully-mechanized excavating machine is not good and the workload is heavy, The section excavation technology, that is, the mud-water balance pipe jacking construction method, and a brief introduction of the operation flow of the mud-water balance pipe jacking construction method and the feasibility analysis of using the mud conveying system in the rock roadway. The mud slag conveying pipe is designed and verified.
