摘　　要：本文以某煤矿1351工作面为例,根据该工作面的具体地质条件,通过分析,确定了合理的支架工作阻力,并确定相应的支护参数。通过对工作面支架初撑力和工作阻力统计分析,可以明显的看到,在复杂煤层的地质条件下,选择的支架在使用过程中控制了断层切割破坏型顶板,支架的承载性能也得到充分发挥,受力状况良好,并能确保工作面安全生产,大幅度提高煤的回收率。该研究成果在同类复杂地质条件下的其它煤矿具有重要参考价值,对复杂的地质条件下综采机械化开采具有指导意义。This paper take the mine 1351 working surfaces as an example, according to this working surface＇s geological condition, had determined the reasonable support working resistance and the corresponding supports and protections parameter. Through initially supports the strength and the working resistance statistical analysis to the working surface support, the results show that under complicated seam＇s geological condition, the choice support controlled the fault cutting destruction roof in the use process, support＇s load bearing performance also obtained the full display, the stress good shape, and the working surface is safe in production. This research results have the important reference value under similar complex geology＇s other coal mine.
