| 摘 要： | 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。

| Abstract: | Based on the characteristics of coal body textures and differences among various coal seams in Nantong Mine, the destroyed inner factors of coal body textures in different coal seams with same geological structure position and its prognosis method are analysed from thickness, texture,coal petrology and coal quality etc.. The controlling action of coal body texture on gas eruption under same geological structure is explained, According to the features and differences among coal body textures in different coal seams,the danger levels of gas eruotion in No.4.5.6 coal seams of this Mine are analysed and annraised. |
