摘　　要：针对303盘区14-3层8307不规则工作面煤层厚度小、倾角大、地质条件复杂,在回采过程回采难度大、煤柱回收率低等技术难题,对8307不规则工作面精细化回采方案进行研究,提出了旋转回采工艺,通过实际应用,旋转回采工艺降低了工作面设备搬家难度,提高煤柱回采量达2.7万t,取得了显著应用成效。Aiming at the technical problems of 8307 irregular working face of 14-3 seam in 303 pan area,such as small thickness of coal seam,large dip angle,complex geological conditions,difficult mining process and low recovery rate of coal pillar,the refined mining scheme of 8307 irregular working face is studied,and the rotary mining technology is put forward.Through practical application,the rotary mining technology is reduced.It reduces the difficulty of moving equipment in working face,increases the recovery of coal pillar to 27,000 tons,and achieves remarkable application results.
