虽然有各种关于煤与瓦斯突出本质和机理的假说,然而所有研究都承认瓦斯因素在突出激发和发展过程中的作用。大量的资料表明,煤与瓦斯突出既可能发生在煤的瓦斯含量较小的条件下( 6～ 8米~3/吨),也可能发生在其含量较大的条件下(25～30米~3/ Although there are various assumptions about the nature and mechanism of coal and gas outburst, all studies acknowledge the role of gas factors in highlighting the stimulus and development. A large amount of data shows that the coal and gas outburst may occur in the coal gas content is small (6 ~ 8 m ~ 3 / t), may also occur in its larger content (25 ~ 30 m ~ 3 /
