摘要
作者对湖南、江西,广西,河南等矿区的一些煤样作了分析研究,揭示了煤的此表面积与影响煤与瓦斯突出的几个主要参数(煤变质程度、煤的坚固性系数、煤的瓦斯放散初速度、煤的吸附瓦斯容量及煤的解吸瓦斯特性)之间的关系。首次提出了以煤的比表面积、瓦斯成分C_2~0及煤中残存瓦斯量作为预测预报煤与瓦斯突出危险的综合指标。
The author analyzed some coal samples from mine areas in Hunan, Jiangxi, Guangxi and Henan provinces. He founds the relation between coal specific surface area and major parameters influencing coal and gas outburst, such as, degree of metamorphism, coal hardness, initial emission rate of methane from coal, methane absorption capacity and desorption properties of coal. Three comprehensive indices are proposed for the first time to predict the risk of coal and gas outburst. They are specific surface area of coal, concentration of C_2° and residual methane in coal.
