摘　　要：针对大倾角煤层综放开采工作面的复杂地质条件,分析了大倾角条件下综采工作面支架与围岩相互作用关系,阐述了围岩特性对液压支架的性能影响,对大倾角煤层开采过程中,支架的受力及稳定性情况进行了研究,为大倾角煤层综放工作面液压支架的设计提供了较好的借鉴作用。Aiming at the complex geologic condition in deep angle inclined top- coal wall, analyzed the reciprocity relationship of fully mechanized top - coal hydraulic support stress state and enclosing rocks under the condition of large dip angle, expatiated the effect on the capability of hydraulic powered support that the en- closing wall characteristic arousing. Studied the stress and the support stability of dip angle fully mechanized top - coal caving support in mining, provided a good model method for the designing of hydraulic powered support in deep angle inclined wall.
