为了掌握淮北煤田瓦斯灾害的主要特征和控制因素，在资料分析、实验测定和理论研究的基础上，对淮北矿区地质演化和瓦斯参数进行了分析。结果表明，淮北煤田位于徐宿弧形构造圈内，煤层和瓦斯赋存状态呈两极分布。构造、构造应力、岩浆侵入和开采深度是瓦斯突出的主控因素。淮北煤田地质条件复杂，突出事故几乎都发生在构造构造带内。水平构造应力在突出事故中起主导作用。岩浆侵入的热演化和圈闭作用控制了煤的物性、瓦斯赋存和突出。随着开采深度的增加，瓦斯突出事故发生的可能性明显增加。经过多次有效的区域治理，瓦斯治理效果明显，保证了突出煤层的安全高效开采。
In order to master the main characteristics and controlling factors of gas disasters in Huaibei coalfield, based on data analysis, experimental determination and theoretical research, we analyzed the geological evolution and gas parameters in Huaibei mining area. The results show that Huaibei coalfield is located in Xu-Su arcuate tectonic circle, and the coal seam and gas occurrence took on bipolar-distribution. The dominant controlling factors of gas outburst were tectonic structures, tectonic stress, magma intrusion and mining depth. The geological conditions of Huaibei coalfield were very complicated, and almost all the outburst accidents occurred in tectonic structure zones. The horizontal tectonic stress played a dominant role in outburst accident. The thermal evolution and trap effect of magma intrusion controlled the physical characteristics of coal, gas occurrence and outburst. With the increase of mining depth, the possibility of gas outburst accidents increased significantly. After carrying out several effective regional measurements, the gas control effect was obvious and could ensure safety and high efficiency mining in outburst coal seams.
