摘　　要：总结了淮北童亭矿区7煤层瓦斯压力及含量分布规律和瓦斯涌出规律并结合实际际地质情况,探讨了在开放性大断层影响下的瓦斯赋存规律:矿井西翼7煤层瓦斯赋存受到了井田边界赵口正断层的决定性影响,赵口断层成为7煤赋存瓦斯的运移通道;童亭矿井西翼7煤层在距赵口断层一定的范围开始,瓦斯涌出量、瓦斯含量、瓦斯压力,随着埋深的增加而减小,距离断层越近,瓦斯含量与瓦斯压力越小,该规律打破了瓦斯赋存随煤层深度增加而增加的一般规律,对该矿突出危险区域划分,瓦斯分区域治理等有一定的指导意义。Based on the real geological event, this paper summarizes the 7 coal seam＇s law of gas pressure and content and the gas emission in the tong ting mine to study the law of gas occurrence influenced by the Zhaokou fault： the 7 coal seam is influenced by the fault definitively, Zhaokou fault becomes 7 coal gas occurrence of migration path, the gas pressure and content and the gas emission reduce with the depth increasing, which will become little with the place gets near to the fault. This rule breaks the general rules that the gas occurrence increases with the depth, the research guided the mine to divide the dangerous re- gion, and it is of great significance to regional management to the gas.
