Considering the relationship between extraction and fire prevention, the main mining coal seams of Xinji No.1 Mine are Seam 13, Seam 11, Seam 9, Seam 8 and Seam 6, all of which have the spontaneous combustion tendency, and the spontaneous combustion level is Ⅱ. The spontaneous combustion period is commonly 3 ~ 6 months. Since its launch in 1993,a total of 16 times of spontaneous fire have occurred. The main involved coal seam is Seam 13. The Seam 8 only has one time of fire accident at the roadway crossing fault. In order to guarantee the safe mining of Seam 13, the coal seam “3 zones” research is carried out and fire prevention measures are determined. This paper introduces the determination of iconic spontaneous combustion gas and carries on the determination of spontaneous combustion “3 zones” in the goaf, and adopts comprehensive fire prevention and control technology. 关键词 ： 一通三防；厚煤层；三带；综合防灭火 Key words: ventilation and prevention；thick coal seam；3 zones；comprehensive fire prevention and control 　　中图分类号：TD752.2 文献标识码：A文章编号：1006-4311（2015）20-0101-04 1概述 131303综放工作面位于1水平三采区（北中央采区）是三采区首采综放工作面，开采的煤层为13-1及13-1下煤层。工作面平均全层厚度7.26m，平均纯煤厚度6.40m，平均含夹矸厚度0.86m，13煤层走向240°～300°，倾向330°～30°，煤层倾角3°～28°，平均15°；工作面南
