联络巷超前探放老空区积水技术研究

Research on Technology of Advance Exploring and Drainage Goaf Water of Crossheading

煤矿老空区水害破坏性大,一旦发生,后果往往很严重,因此采空区积水的探放工作至关重要。在分析陈四楼煤矿水文地质条件的基础上,依据《煤矿防治水规定》,对超前探放水钻孔进行设计,根据施工要求制订了安全技术措施,利用21501联络巷对21304采空区积水进行超前探放水,并取得了良好效果。

Hazard of goaf water in coal mine is huge, once it happens, the consequences are often very serious, so exploration work of goal water is crucial. Based on analysing the hydrogeological condition of Chensilou Coal Mine, and according to ＂ Provisions for Mine Water Prevention and Control＂, the boreholes of advance water exploration and discharge were designed, safety technology measures were also laid down according to the demands of construction. 21501 crossheading was used to carry out advance water exploration and discharge in goaf of 21304 working face. The effects were proved to be very good.
