The intermolecular force of deformed coal is relatively small, the deformed coal has low strength and high adsorption capacity, and those determine the outbreak ofcoal-gas outburst.
构造煤分子间的作用力小，决定了构造煤强度低和吸附性能高，从而控制了煤与瓦斯突出灾害的发生；

Adsorption capacityof outburst coal is strong, desorption velocity is very fast too. It can form very high gas pressure which enhance destructiveness of coal-rock.
