摘　　要：本文讨论了煤与瓦斯突出过程中煤体的破坏规律，分析了破坏机理、推导了煤层中被破坏煤体的数学分布函数，给出了分布函数中有关常数的求值方法，并对另布函数进行了试验验证．The law and mechanism of the coal-body destruction are analysed in this paper. On the basis of the theory of statistical strength, a distribution function of the coal-body destruction is worked out. A way to get the value of the two constants of the function is also presented. Finally, some experiments are performed to sapport the hypothesis.
