随着开采深度及范围的扩大,邢台煤矿井下高压出水点越来越多,既浪费了大量的排水费用,又对岩溶水环境和水资源造成了严重破坏。针对上述情况,用四种不同的方法分别进行了封堵和重新利用,使矿井减少了480m~3/h的无效排水,经济效益和环保效益均十分明显。 With the expansion of mining depth and scope, more and more high-pressure discharge points in Xingtai coal mine are not only wasting a lot of drainage costs, but also causing serious damage to karst water environment and water resources. In view of the above situation, blocking and re-use were carried out by four different methods respectively, which reduced the ineffective drainage of 480m ~ 3 / h in the mine, and the economic and environmental benefits were all obvious.
