摘　　要：采煤工作面在生产过程中需要进行调面回采。通过选择合理的工作面与运输巷应取夹角和调面方案,采用楔形调面法,将工作面与两巷调整到合理的几何状态;从而提高了生产效率和回采率,取得了良好的经济效益。A coal mining face would be required to have a face adjusted mining during the coal production process.With the coal mining face and the transportation gateway rationally selected with the intersection angle and face adjusted plan,the wedge face adjusted method was applied to adjust the coal mining face and the two gateways into a rational geometric status.Therefore the mine production efficiency and the mining rate could be improved with good economic benefits.
