摘要
本文简述了煤分子结构统计分析的原理,并用这种方法研究了南桐煤矿煤的分子结构及其随煤变质加深的变化规律.同时,还探讨了用煤大分子结构异常特征预测煤和瓦斯突出潜在危险性的问题。
This paper describes the principal of statistical analytical method of macromolecular structure of coal. By using this method, the macromolecular structural indices of 13 coal samples are presented. The law of variation of macromolecular structure of coal with the increase in the degree of metamor-phism of coal is gained, which is served as a good result of this research work. At the same time, the author also discusses the question that the hazard of outburst in colliery is predicted by using the abnormal features of the maro-molecular structure of coal.
