中文摘要：
通过实际观测采空区浮煤状况、工作面推进速度和采空区进回风侧02浓度的分布规律，根据“三带”划分方法及划分指标，对白羊岭煤矿15101综放工作面进行了“三带”划分，掌握了采空区煤自燃“三带”分布规律及危险区域。15101工作面散热带的分布范围在采空区距离工作面10～100m，进风侧由于漏风强度较大，散热带宽度较宽。窒息带在距离工作面165m以上的采空区深部；在工作面回风侧，窒息带的深度约为137m。氧化升温带宽度在工作面进风侧最大，达到55m左右。
英文摘要：
Division of spontaneous combustion ＂three Zones＂ in 1510 fully mechanized top-coal caving face in Baiyangling Mine was conducted through the actual observation of the float coal status in the gob, the face advance speed and the distribution law of oxygen concentration on the air intake and return side of the gob and according to the division method and index of spontaneous combustion ＂three zones＂, and the distribution rule of coal spontaneous combustion ＂three zone＂ and the danger zone in the gob were kept abreast. The distribution range of the heat radiating zone in 15101 working face was within 10 to 100 m from the gob, and the heat radiating zone on the air intake side was wider due to stronger air leakage. The choking zone was in the deep part of the gob 165m away from the working face. The depth of the choking zone on air return side was about 137 m. The oxidation temperature-rise zone was the widest on the air intake side of the working face, it was about 55 m.
