摘　　要：望田煤矿开采11号、13号、13_下号煤层。11号煤层、13号煤层一采区采用综采工艺,13号煤层二、三采区采用综采放顶煤工艺,技术上可行、经济上是合理,有利于实现高产高效安全生产。工作面布置在首采区内,采区内采用前进式开采,回采工作面采用后退式回采,采区回采率可达75%。In Wangtian Mine, No.11, No.13, and No.13b seams could be mined. The first mining areas of No.11 and No.13 could use fully-mechanized mining technology, while for the second and third mining areas of No.13, top coal fully-mechanized mining could be used, feasible in technology and reasonable in economy, which could realized the safe and efficient production. When working face is in the first mining area, advancing mining is adopted in the mining area and retreat mining in the caving face, with recovery rate of 75%.
