摘　　要：对于大倾角复合顶板综采工作面机械化开采存在的煤壁片帮、顶板冒落问题,以山西某煤矿为研究背景,其北翼3号煤层为大倾角中厚煤层,以该煤层的开采条件(大倾角、复合顶板)为基础,展开了综采工作面液压支架的选型工作,同时针对大倾角液压支架的防滑、防倒以及防飞矸等技术问题展开了研究,并将其成功应用到实际生产中。With regard to the problems existing in mechanized mining of the fully mechanized mining face with large dip composite roof,taking a coal mine in Shanxi Province as the research background,the No.3 coal seam in the north wing is a medium thick coal seam with large dip angle.Based on the mining conditions of the coal seam(large dip angle and composite roof),the selection of hydraulic support for the fully mechanized mining face was carried out,and the technical problems of anti-slip,anti-fall and anti-fly waste of the hydraulic support with large dip angle were also studied.It has been successfully applied to practical production.
