  3. For the tectonic coal , the properties of higher porosity and lower permeability make it capable of keeping higher gas pressure ; both of the “ isolating action ” and “ gas - cushion action ” cut down the resistance against outburst ; the specifity of high - defomed - extent makes desorption , escape and flowing quickly become possible ; the existing of weak - seam or “ thoroughfare - seam ” create suitable conditions for the initial erupting and continued developing of coal and gas outburst. on the whole , it is the synhesis action of all factors , which leads to outbursts. the existing of tectonic coal with certain thickess is the essential condition of coal and gas outbursts , but not the sufficient condition

    高空隙率、低透氣性使構造能夠保持較高的瓦斯壓力;破碎性、 「隔離」作用及「氣墊」作用,使構造抵禦外力作用的能力大大降低;構造形幅度大的特性,為瓦斯的迅速解吸、放散和快速流動創造了條件;構造薄弱分或「通道」的存在,則為與瓦斯突出的初始激發和持續發展奠定了基礎;上述因素的共同作用,影響和制約了與瓦斯突出的強度和分佈.盡管如此,一定度的構造的存在只是發生與瓦斯突出的必要條件和有利條件,而非充分條件
