摘要
河曲旧县露天煤矿现采用的引水圈集中排水方式存在排水投入高、管理过程繁琐、需要随采场开采频繁迁移等问题,同时在排水过程中容易引起采帮岩层扰动。因此,为了改进该矿排水方式,对其排水系统进行改进设计。主要是通过布置集水井,以降低采场地下水位、减小排水对采场帮的影响。实践表明,改进后的排水系统在采场排水中取得了显著应用效果。
This paper puts forward the problems of high drain age input, tedious management process and frequent migration with stope mining in the centralized drainage mode of open pit coal mine in Hequ old county. In order to improve the drainage mode of mine, the paper discusses the optimization of drainage system. By arranging the collecting well, it can not only reduce the underground water level of stope, but also reduce the influence of drainage on stope gang, and obtain remarkable application effect in stope drainage by new drainage system.
