我矿黄沙矿区是由四组脉带组成的矿床。过去由于分采与合采的界限未很好解决,多年来一直使用浅孔留矿法进行分采,致使部分采场间夹墙产生不同程度的丢脉损失。无产阶级文化大革命以后,我矿遵照毛主席“开发矿业”的教导,组织有老工人、领导干部、技术人员三结合,对该矿区16号脉带原来已确定分采的两个采场进行了解剖调查,认为该两采场间夹墙矿脉密集,含脉 My mine Huang Sha mining area is composed of four groups of pulse deposits. In the past, because the boundaries of sub-mining and co-mining were not solved well, the shallow hole stay-mining method has been used for sub-mining for many years, resulting in some losses of the lost circulation in some of the stope walls. After the Great Proletarian Cultural Revolution, our mine followed the teachings of Chairman Mao “Development of Mining ” and organized the three old stratums, leading cadres and technicians to combine the two stopes that had been determined to be separated in the 16th pulse of the mine area To understand the anatomy investigation, that the two mining field between the wall with dense vein, with pulse
