摘　　要：借鉴我国急倾斜煤层水平分段综采放顶煤与巷道放顶煤开采技术，提出了3.5～10m大倾角煤层巷柱式放顶煤采煤法。对该采煤方法的巷道布置、阶段顶煤高度以及回采工艺进行了研究，形成了巷柱式放顶煤开采技术。With the fully mechanized horizontal sectional top coal caving mining technology and the gateway top coal caving mining technology for deep inclined seam in China for reference, the paper provided a gateway and pillar top coal caving mining method for deep inclined seam with a thickness between 3.5 to 10 m. The paper studied the gateway layout, the sectional top coal height and the coal mining technology of the coal mining method. Then the gateway and pillar top coal caving technology was developed.
