介绍了燃烧临界限改进值的由来，根据Ｋｕｋｕｃｚｋａ法原理编制了计算程序，用于推算煤矿气体的燃烧界限．通过计算和验证，指出该方法不符合ＬｅＣｈａｔｅｌｉｅｒ定律．在保留该方法特点的基础上，对其进行了修正，消除了可能出现的差错．通过与其他方法计算结果的比较，指出修正法在应用中具有较高的安全性．
This paper introduces the origin of combustion critical limit value improvement and compiles a calculation program based on Kukuczka principle to calculate the combustion limit of coal gas. Through calculation and verification, it is pointed out that this method does not comply with LeChatelier’s law. On the basis of preserving the characteristics of this method, it has been amended to eliminate the possible mistakes. By comparing with other methods, it is pointed out that the correction method has high safety in application.
