摘　　要：通过建立综放采空区三维自然发火预测模型,采用数值模拟软件对高瓦斯煤层抽放条件下综放采空区漏风状况进行了数值模拟,利用模拟结果对采空区进行了煤自燃"三带"的划分,并分析了该工作面采空区浮煤自燃的危险区域及危险程度,可用来指导具有类似情况的采空区浮煤自燃火灾的防治工作。Based on the establishment of three-dimensional spontaneous combustion prediction model for the gob of fully-mechanized caving face,numerical simulation on the breathing of the gob of fullymechanized caving face of high-gassy coal seam was conducted by using numerical simulation software under gas drainage condition,'Three-zones' of spontaneous combustion of coal were divided according to the simulated results,and the dangerous zone and degree of spontaneous combustion of float coal in the gob of this face were also analyzed,which can be used to guide the prevention and control work of spontaneous combustion of float coal in the gob of the face with similar conditions.
