摘要
针对15111运输顺槽掘进过程中受上覆K2含水层影响,顶板出现淋水现象,导致巷道顶板软化严重、顶板支护难度大、巷道掘进效率差等技术难题,通过对15111顺槽上覆含水层采取合理有效的探放水设计,并采取了相应的安全技术措施。从实际应用效果来看,采取探放水措施后消除了上覆裂隙含水层水害隐患,取得了显著应用成效。
Due to the influence of K2 aquifer on the roof of 15111 haulage gateway during driving,which leads to serious roof softening,difficult roof support,poor driving efficiency and other technical problems,reasonable and effective water exploration and drainage design is adopted for the aquifer on 15111 haulage gateway,and corresponding safety technical measures are taken.From the perspective of practical application effect,the hidden danger of water disaster in overlying fractured aquifer is eliminated after taking water exploration and drainage measures,and remarkable application effect is achieved.
