摘　　要：综合我国急倾斜煤层水平分层综采放顶煤和水平分段巷柱式放顶煤两种采煤方法的技术优点，提出在厚度10～20m的急倾斜煤层内使用”巷柱-综采放顶煤”开采技术。介绍了该采煤方法的巷道布置、通风系统、回采工艺，以及阶段高度确定、煤层弱化、防灭火等关键技术。Refencing these advantages which are fully mechanized top cawing mining and gateway and pillar top coal caving for steep inclined thick or special thick seam in China, from that, the paper put forward a combin gateway and pillar with fully mechanized top cawing mining technology in steep inclined special thick seam with a thickness form 10 to 20 m. The paper also introduce it＇s the gateway layout of cawing mining technology, the system of ventilantion, the coal mining technology; as well as studied these key technologies： making certain the hight of top coal, weaking of coal, precaiction and extinguish a fire etc.

关 键 词：急倾斜煤层 综采放顶煤 巷柱式放顶煤 巷柱-综采放顶煤 采煤方法
