摘要
从块矿结构参数、块矿技术指标等方面比较了普通浅孔留矿法、超前槽采矿浅孔留矿法的优缺点,介绍了河北省涞源县镰巴岭铅锌多金属矿矿床的地质及构造特征,矿区的水文地质条件及开采条件,认为在矿体较连续且厚度在0.8～2 m地段采用超前槽采矿浅孔留矿法较经济合理。镰巴岭铅锌多金属矿采用超前槽采矿浅孔留矿法开采,取得了较好效果。
From the fields of structure parameters and technical index of lump ore,it is compared the strong and weak points of shallow hole shrinkage stoping of normal and pilot shaft sinking,introduced the geologic and structural features,hydrogeology and mining condition of mining area in Lianbaling Lead-Zinc Multi-Metal Mine of Laiyuan County of Hebei Province,considered that it is rather economic and reasonable to adopt shallow hole shrinkage stoping of pilot shaft sinking in the area with relatively continuous orebody and thickness being within 0.8～2 m.In this mine the method make a rather good result.
