摘　　要：为了安全生产,露天煤矿一般将地下水抽排到境界外,这将对生态系统和生态环境带来巨大影响。在充分调研矿山开采状况及水文地质资料的基础上,分析了主要含水层的赋存状况,根据其特点设计了露天煤矿保水开采的防水帷幕施工参数,并对施工效果进行了系统检测。结果表明,高压喷射法对岩层水防渗具有良好效果,可应用于露天矿山的地下水治理,并有利于生态环境的可持续性发展。Considering the production safety of open-pit coal mine,the groundwater is usually extracted out of the pit limit,which will greatly influence the ecological system and environment.Based on the thorough investigation of mining conditions and hydrogeological data,the paper analyses the occurrence condition of the main aquifer;then according to the characteristics,it designs the waterproof curtain construction parameters under the condition of groundwater retention.And the construction effect is also tested systematically.The results show that high pressure jet grouting has good effect on controlling seepage of rock water,which can be applied to groundwater management in open-pit coal mine and will be beneficial to the sustainable development of the ecological environment.
