南桐煤矿为一高沼气严重突出矿井。该矿煤层厚度的变化对其瓦斯突出有很大影响,无论是厚度不同的三个可采煤层间的对比,还是同一煤层不同厚度区段的比较,都明显地反映出煤层厚度同煤与瓦斯突出危险程度呈正相关关系。
Nantong Coal Mine is a high-profile gas station. The variation of coal seam thickness has a great influence on its gas outburst. The comparison between the three recoverable coal layers with different thicknesses or the comparison of different thickness sections of the same coal seam clearly shows that the thickness of coal seam is similar to that of coal and coal The degree of gas outburst is positively correlated.
