摘 要:为了提高矿井煤炭资源回收率,减少资源浪费,对淮南矿业集团潘一矿井田范围内的呆滞煤量进行圈定。建立呆滞煤量台账,并对其进行可采性评估后布置工作面进行回采。通过优化采场接替方案、开采呆滞煤量,使得矿井年产量由460万t增至500万t,提高了回收率,缓解了采场接替紧张的局面。In order to improve the recovery rate and reduce waste of resources,the area of leftover coal was determined within the field of Panyi Coal Mine. A standing book of left over coal was established. And the working face was arranged after the workability of coal was evaluated. Through the optimization of stope replacement,the leftover coal was exploited,increasing the annual output from 4. 6 to 5 million tons. The recovery rate was improved and the difficulty of stope replacement was alleviated.
