| Abstract: | 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 k... |
| Keywords: | steep inclined seam fully mechanized top cawing mining gateway and pillar top coal caving combin gateway and pillar with fully mechanized top cawing mining coal mining method |
