摘要
针对四台矿303盘区采空区积水问题,结合盘区的水文地质情况,确定防治水方案和注浆孔布置,分析研究具体的注浆施工工艺,并采用钻探方法对注浆效果进行验证。结果表明,通过对303盘区注浆封堵,有效隔绝14号303盘区积水通过3条盘区巷渗出,解决了303盘区水患问题,盘区水位稳定,每年可节省资金356.4万元。
Aiming at the problem of goaf water accumulation in 303 panel of Sitai Mine,combined with panel hydrogeological conditions,the water prevention and control plan and grouting hole layout were determined.The specific grouting construction technology was analyzed and studied,and the grouting effect was verified by drilling method.The results showed that through the grouting sealing of 303 panel,the water accumulated in No.14303 panel could be effectively prevented inflow through three panel roadways,and the water damage in 303 panel was solved.The water level in the panel was stable,and the fund of 3.564 million yuan could be saved every year.
