摘　　要：在矿井中,绝大部分自燃火灾由采空区漏风引起。针对采空区各种漏风风流的状况,应用不同的示踪技术和方法进行检测,可以估计出矿井中的漏风通路,以判断漏风方向、计算漏风风量、划定自燃危险区域等,为防治采空区煤炭自燃,保证采煤工作面安全生产提供了依据。Majority of spontaneous combustion caused fires in coal mines are the results of air leakage in gob areas. According to various air leakage conditions in coal mine gob areas, varied tracing technologies and tracing methods are used to test the rout of air leakage, directions of air leakage, calculation of air leakage and identification of areas of spontaneous combustion. This practice provides sufficient assistance to the prevention and control of spontaneous combustion in gob areas and work safety in coal mine faces.
