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、低透氣性使構造煤能夠保持較高的瓦斯壓力；破碎性、 「隔離」作用及「氣墊」作用，使構造煤抵禦外力作用的能力大大降低；構造煤變形幅度大的特性，為瓦斯的迅速解吸、放散和快速流動創造了條件；構造煤薄弱分層或「通道層」的存在，則為煤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，影響和制約了煤與瓦斯突出的強度和分佈.盡管如此，一定厚度的構造煤的存在只是發生煤與瓦斯突出的必要條件和有利條件，而非充分條件 -
