Application of drainage way by the hole in roadway in Yuanbaoshan Open-pit Mine

摘要: 以元宝山露天煤矿为实例,总结了对煤系上覆砂岩、泥岩互层,分布不连续的基岩含水层采用巷道泄水孔疏干方法的施工经验,提出该方法在同类地区具有推广价值

Abstract: Based on the case study of Yuanbaoshan Open pit Mine,it is summarized that the experience of using the discharge way by the hole in roadway to conduct drainage from the overlying sandstone,mudstone and discontinuous distributed basement aquifer.This discharge way is valuable to spread in other areas with the same geological conditions.
