摘要

受特殊地理位置和构造影响,东明露天矿地下水补给强烈,边帮涌水下切侵蚀边帮,影响边帮稳定。通过开展激发极化偶极勘察,初步查明地下水的异常分布,采用靶区布井方式替代等距井排布置,优化了降水井布置方式及成井工艺参数,开展针对性降水。通过对近2年来防治水数据、截流疏干效果和成本控制等论述,进一步验证了激发极化偶极手段优化降水井布置的可行性和有效性。
        Dongming open-pit mine is affected by its special geographic location and structure, the groundwater runoff recharge is strong, and the pit slope is eroded by the side wall gushing under water, which affects the pit slope stability. The abnormal distribution of groundwater was preliminarily identified by induced polarization dipole survey, Through carried out target area well layout was used instead of equidistant well row layout, the layout mode and completion parameters of precipitation wells were optimized, and targeted precipitation was carried out. The feasibility and validity of optimizing the layout of precipitation wells by induced polarization dipole method are further verified by discussing the data of water control, closure and drainage effect and cost control in the past two years.
