摘 要:针对金刚煤矿412采区开采近距离大倾角极薄煤层丢失资源严重的情况,依据采煤工作面“下三带”分布规律,采用俯伪斜跨上山开采方法对412采区采方案及回采工艺进行改进,并通过现场矿压观测。结果表日月:俯伪斜跨上山开采是可行的。利用的方法实现了不留护巷煤柱采煤,提高了采区回采率,俯伪斜跨上山开采方法的成功为条件类似的薄煤层矿井具有重要的指导意义。Based on the serious condition of losing resource during the close quarter, large angle and ultra-thin coal-seam was being mined, and according to the distribution law of coalface "down three zone", the mining method of pitching oblique layer in raise direction was used in 412 mining area and the mineral pressure was field observed. The result showed that the mining method of pitching oblique layer in raise direction was feasible.By using of this method, mining without preserving protection pillar was realized and working section recovery was improved. The success of the mining method of pitching oblique layer in raise direction can provide important guiding role for thin coal seam mines with similar conditions.
