摘　　要：结合兼并重组后的龙峰煤矿实际情况,分析了矿井的地质构造、煤层赋存状况、煤层厚度及硬度、煤层结构、顶底板条件等,最终确定10105工作面更适合采用综采放顶煤采煤法。研究了10105工作面综采放顶煤开采工艺参数,包括采煤机割煤高度和采放比、放煤步距与采煤机截深、初次放煤步距、放煤方式、端头放煤以及工作面末采放煤等。结果表明,综采放顶煤开采更有利于矿井的安全高效开采,有利于提高煤炭资源回收率,可为类似赋存情况煤层的开采方法提供了借鉴。According to the actual situation of Longfeng Coal Mine after the merger and reorganization,as well as the analysis results of the geological structure,coal seam occurrence,coal seam thickness and hardness,coal seam structure,roof and floor conditions of the mine,it is more suitable for the 10105 working face to apply fully mechanized top coal caving mining method. The technological parameters of fully mechanized top coal caving in 10105 working face are studied,including shearer cutting height and mining-caving ratio,caving interval and shearer cutting depth,initial caving interval,caving method,end caving and terminal caving. The results show that fully mechanized top coal caving is more conducive to the safe and efficient mining of the mine,and to improving the recovery of coal resources,which can provide references for coal seam mining with similar occurrence conditions.
