为了研究矿井涌水规律,为以后工作面开采时矿井防治水提供参考依据,米箩矿在首采面开采时,进行了矿井涌水规律实测。采用经验公式法、物理模拟及数值模拟法,合理确定了防水安全煤岩柱尺寸,目前首采面已回采结束,未发生透水事故。通过矿井涌水量实测,分析了矿井涌水量与降雨量、开采面积、顺槽排水量的关系,总结了矿井涌水量与降雨量、开采面积、顺槽排水量的规律。
In order to study the regularity of mine water gushing and to provide a reference for prevention and control of water in mine after mining face, the mine gushing water law was measured during the mining of the first mining face. Empirical formula method, physical simulation and numerical simulation method, reasonably determine the waterproof coal pillar size, the first mining face has been the end of the mining, flooding did not occur. Through the measurement of mine water inflow, the relationship between mine water inflow and rainfall, mining area and cistern displacement was analyzed, and the law of mine water inflow and rainfall, mining area and cistern drainage were summarized.
