扇形工作面回采工艺研究

Research on Coal Wining Technique of Sector Working Face

对扇形工作面回采工艺进行了深入研究,并在南屯煤矿三采区实现了扇形工作面的成功布置与回采,使煤炭资源得到了最大限度的回收,为矿井边角煤开采探索出了一条新路。

Through researching of recovery technics on the sector working face, with the successful disposal and recoveryachieved on the sector working face at the Third Picking Section of Nantun Coal Mine, A new way for the coal exploitation are explored at margin and comer of the mine. The coal resource are furthest reclaimed.
