摘　　要：探讨了采空区漏风与自燃点的分布规律，分析了悬空密闭阻燃防漏机理，介绍了悬空密闭设计参数与特点以及在现场应用效果。分析和实践表明，在采空区进出风侧砌筑悬空密闭是防止煤炭自燃的一项既经济又有效的简便措施，把它与均压灌洒浆等措施结合起来，效果更为明显。： The paper inquired into the distribution law of air leakage and combustion ignition temperature in the gob area, analyzed the flame-retarding and leakproof mechanism of the suspended fire stopping, described the design parameters and characteristics of suspended fire stopping and its site application effect. The analysis and practice show that to build suspended fire stoppings at both intake and return air sides on the gob area to prevent spontaneous combustion of coal is an economic, effective and simple measure, especially when it is combined with measures of fireproof by even air pressure, grouting and spraying.
