水文地质复杂的非煤矿山防治水设计与应用

Design and Application of Water Control in Non-Coal Mine with Complex Hydrogeology

该文根据非煤矿山水文地质复杂类型,结合矿山探矿实际工程应用情况,分析了非煤矿山大断面巷道水文地质复杂探放水设计、施工以及注浆治理的可行性,为未来水文地质复杂性矿山治理水害提供了参考。水害治理是实现矿山安全生产的重要抓手,水文复杂矿山是现有地下矿山的管控重点,该文说明了5m左右大断面情况下的防治水探放设计,在围岩稳固情况较差的情况下,开展了注浆施工,介绍了注浆压力的设计,注浆的前期、中期、后期的全过程管理,介绍了实际工程参数和设计参数以及压水试验,对类似矿山开展水害的防治提供了很好的参考价值和应用前景。

According to the hydrogeological complex types of non-coal mines,combined with the actual engineering application of mine prospecting,this paper analyzes the feasibility of water exploration and drainage design,construction and grouting treatment of non-coal mines with complex hydrogeological conditions in large cross-section roadway,which provides a reference for the future hydrogeological complex mine water disaster treatment.Water disaster control is an important means to realize safety production in mines,and hydrologic complex mines are the key point of management and control in existing underground mines.This paper describes the design of water exploration and drainage under a large section of about 5m,under the condition of poor stability of surrounding rock,the grouting construction is carried out,and the design of grouting pressure and the whole process management of the early,middle and late stages of grouting are explained,the actual engineering parameters,design parameters and pressure water test are introduced,which provides a good reference value and application prospect for water disaster prevention and control in similar mines.
