摘　　要：针对矿区煤层赋存条件较为复杂的特点,采用滑移支架放顶煤开采替代∏型钢梁与单体液压支柱配套支护放顶煤开采,有效解决了支护不及时、支护稳定性差、工艺复杂和工人劳动强度大的问题,取得了良好的社会效益和经济效益。this paper stated the complex characters of coal seams in coalfield, using sliding caving chock mining technology in stead of ＂П＂ beam and single hydraulic stanchion mining technology, it solving the problems of roof being supported was not in time, supporting system being instable, the technology being complex and big physical work for miners, resulting in good social and economical benefit.

关 键 词：滑移支架 支护设计 放顶煤工艺 优越性分析
