一、地质特征该锰矿矿床产于二叠纪乐平煤系的底部,白泥塘层的上部,呈单一层状产出,属倾斜薄矿体。该矿曾在西部矿段的S_5~S_6勘探线之间、869~886中段巷道中的69111和69112矿块作过长壁崩落法试验。根据试验中揭露的地质矿床方面资料来看,矿体倾角一
First, the geological characteristics of the manganese ore deposits at the bottom of the Permian Leping coal system, the upper part of the Pak Nai Tong, was a single layer of output, is inclined thin ore body. The mine had been subjected to a longwall caving test between the S_5 ~ S_6 prospecting lines in the Western Mines and the 69111 and 69112 mines in the middle 869 ~ 886 tunnels. According to the data of geological deposits revealed in the experiment, the orebody inclination is one
