摘　　要：为提高煤炭资源的回收率,在新星煤业8103工作面进行综放工作面调采技术实践。8103工作面与设计调斜线之间的夹角为12.8°,运输顺槽需要超前回风顺槽推采35 m。确定了75号架、35号架和机头3个点为旋转中心。通过制定详细的技术措施,实现了安全调采,多回收煤炭资源2.7万t,取得了显著的经济和社会效益。In order to improve the recovery rate of coal resources,the mining technology practice of fully mechanized caving face is carried out in No.8103 Face of Xinxing Coal Industry.The angle between No.8103 Face and the designed diagonal is 12.8°,and the advance return air along the transport chute is required to push the mining by 35 m.The three points of 75#frame,35#frame and head are determined as the rotation center.Through the formulation of detailed technical measures,the safe mining is realized,and 27000 tons of coal resources are recycled,which has achieved remarkable economic and social benefits.
