摘　　要：针对大倾角综采放顶煤工作面液压支架工作状况的特殊性,采取了提高液压支架有效支护可靠性的措施,经过在某煤矿急倾斜特厚易燃煤层工作面的现场实践,效果良好,有效解决了倾角45°左右厚煤层机械化长壁综放开采的技术难题,为急倾斜特厚易燃煤层安全高效开采探索出一条成功之路。Aiming at the particularity of working conditions of the hydraulic support in deep inclined seam and fully mechanized top coal caving face, the measures improving the effectively supporting reliability of hydraulic support are adopted. The practical application in the deep inclined thick and combustible coal seam in a coal mine shows that the effect of field usage is good. This support effectively solves the technical problem to the thick coal seam tilting angle about 45 ° and fully mechanized longawall mining, which provides a successful method for the safe and efficient mining in the deep inclined thick and combustible coal seam.
