掘进巷道顶板综合防治水技术

Integrated Water Prevention Technology of Tunneling Roadway Roof

摘要: 为了减小山西某矿10^#煤顶板采空区积水危害，在掘进10^#+11^#煤联合巷道时，以加强顶板水探测为基础，采用深孔排水、“深孔+浅孔”注浆、留设观察孔等针对性措施对巷道顶板水进行综合治理。

Abstract: In order to reduce water hazards of 10^# coal roof goaf of a mine in shanxi, on the basis of strengthening the roof water detection, deep hole drainage, "deep hole + shallow hole" grouting, setting up observation hole and other targeted measures are used for integrated management of roadway roof water in tunneling 10^#+11^# united coal roadway.
