摘　　要：煤层瓦斯分布具有规律性和差异性。煤与瓦斯突出矿井受地质构造对瓦斯保存和运移作用的影响,存在瓦斯含量较小的非突出区域和瓦斯含量相对较大的突出区域。通过对突出和非突出区域的划分,针对不同瓦斯赋存情况的区域采取不同级别的防突措施,有利于保证防突投入的有效利用,保障矿井安全生产。The distribution of coal seam gas has regularity and difference.Coal and gas outburst mines are affected by geological structure on gas preservation and migration,there are non outburst areas with small gas content and outburst areas with relatively large gas content.To divide the outburst and non outburst areas,and take different levels of outburst prevention measures in different gas occurrence areas is conducive to ensure the effective use of outburst prevention input and ensure the safety of mine production.
