井下突水是煤矿生产中经常遇到的“五大”灾害之一 ,一旦突水 ,治理方法分两大类—疏、堵。死水易治 ,活水难堵 ,因为井下活水补给源充分 ,有流动性 ,一般活水都必须综合治理。本文首先利用水质化验及联通试验 ,查清水源 ,在此基础上综合运用了单、双液浆改造底板、挡水墙设计、夹缝注浆及迎头综合注浆封堵等手段 ,通过施工检查孔验证 ,效果明显
Water inrush from underground is one of the “five major” disasters often encountered in the production of coal mines. Once the water inrush occurs, the management methods fall into two categories: sparse and blocked. Easy to cure dead water, hard water blocking, because underground full of recharge water supply, mobility, the general live water must be comprehensive management. In this paper, first of all, the use of water quality testing and China Unicom test to identify the source of water, on the basis of the comprehensive use of single and double slurry to transform the floor, retaining wall design, grouting grouting and head integrated grouting and other means of closure through the construction inspection hole Verification, the effect is obvious
