摘　　要：介绍了工作面概况、回采工艺及收到的效果等。The lst team of fully mechanization coal mining at Xingtai Coal Mine, Xingtai Coal Bureau in Hebei province, successfully worked out initial fan-shaped section formed by inclined longwall mining at №22304 fully-mechanized face and got good technical anh economical benefits. After working out the initial fan-shaped section of coal face, Drive-head and driven tail end of conveyor were moved forward 12 m and 58m respectively.With saving 60 manshifts, output from initial fan-shaped section is 25000t.No accidents have happened for extracting the section. The paper explains general description of face, technical process of working out the initial fan-shaped section, problems happened during actual mining and adopted measures to solve the problems.The author briefs benefits of working out initial fan-shaped section.
