摘　　要：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。The comprehensive tunneling machine drilling technology is adopted to the coal mine high alley construction. However, in the actual operation process, because of the long distance of roadway and difficult drilling, the comprehensive tunneling machine works in poor environment. To solve the problem, a new type of whole section tunneling technology in coal field,namely slurry balance pipe jacking construction method is put forward. The operation the slurry balance pipe jacking construction method is briefly introduced and feasibility application in the mud conveying system is analyzed. Calculate the size of pipeline which moving the stone of mud slag and the verification is also done.
