the development of tectonically deformed coal is studied, and its relation with dangerous of coal and gas outbursting is primarily discussed.
分析构造煤的分层特征,研究该煤层的构造煤发育特征,并初步探讨了构造煤发育特征与瓦斯突出危险性之间的关系。
the adsorption-desorption isotherms of deformed coal are irreversible, and this irreversible degree increases with increasing extent of the damage of coal.
变形煤吸附-解吸不可逆,解吸滞后;随着煤的破坏程度增加,煤的吸附-解吸不可逆程度加大。
therefore, the characteristic of results of this adsorption-desorption experiments are due to the combined effects of the unique pore structure of deformed coal and water content.
分析表明,变形煤表现出的吸附-解吸新特性,是变形煤特有的孔隙结构和水分含量的差异综合作用的结果。
the intermolecular force of deformed coal is relatively small, the deformed coal has low strength and high adsorption capacity, and those determine the outbreak of coal-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;
the development of tectonically deformed coal may qualitatively reflect hazard of gas outburst.
构造煤的发育程度可以定性的反映瓦斯突出危险性。
the tectonically deformed coal with special petrographical features and compli- cared origin developed in south china.
我国南方构造煤发育,具有特殊的煤巖特征和复杂的成因。
the deformed coal controls the occurrence and the handling of gas disaster.
构造煤控制着煤矿瓦斯灾害的发生与治理。
