本文在系统研究南桐煤矿不同煤层煤体结构特征及其差异性的基础上,从煤层厚度、结构、煤岩、煤质等方面,分析了相同地质构造部位不同煤层煤体结构破坏的内在因素及其预测方法。阐述了在地质构造基本相同的情况下,煤体结构对瓦斯突出的控制作用。根据不同煤层煤体结构特征及其差异性,对该矿4~#,5~#,6~#煤层瓦斯突出的危险程度进行了分析和评价。
Based on systematic study of the structural characteristics and differences of coal seams in different coal seams of Nantong Coal Mine, this paper analyzes the inherent factors of the destruction of coal seams in the same geological structure from the aspects of coal seam thickness, structure, coal rock and coal quality. And its prediction method. Expatiates on the control effect of coal structure on gas outburst with the same geological structure. According to different coal seams structural features and their differences, the dangerous degree of gas outburst in 4 ~ #, 5 ~ #, 6 ~ # coal seams in this mine is analyzed and evaluated.
