| Abstract: | 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. |
