摘　　要：七改煤柱工作面地质条件复杂,在回采过程中工作面需要仰采260 m,仰采角度平均30°,最大36°。在仰采过程中工作面需最难控制的是工作面顶板管理、支架溜子拉移困难、煤机割煤装煤困难、煤壁片帮困难。针对这些问题,工程技术人员展开技术攻关,总结了综放工作面仰采和煤壁片帮治理技术,为今后类似的工作面增补了实践经验。Qigai coal pillar working face faces complicated geological conditions, overhand mining with 260 m is needed in the recovery, average overhead mining angle is 30° , maximum 36° . Working face roof management, difficulty of support movement, mining machine cutting and loading, coal wall rib spalling were the most difficult control. Based on this problem, engineering and technical staff developed technological breakthrough, overhead mining and coal wall rib spalling full-mechanized caving mining face control technology was summarized, which effectively solved overhead mining working face technology problem and provided practice and experience for similar working face.
