Based on coal seam II, coal-and-gas outburst characteristics in the southern Taihang Mts. eastern foot coalfields, applied integrated coal-and-gas outburst hypotheses, from coal gas generation, migration and accumulation points of view, analyzed and studied impacts on coal seam gas parameters and gas outburst factors of coal seam coal quality, hydrocarbon generation capacity, gas content and pressure from factors of magmatic hydrothermalism, geological structure and coal seam buried depth etc. The study has ascertained that the magmatic hydrothermalism has a strong impact on gas outburst; while factors of geological structure, coal seam buried depth have medium to fairly general impacts. The conclusion has provided theoretical basis for geological exploration, coalmine design, production planning and coalmine gas control.%根据南太行东麓二1煤层煤与瓦斯突出特征,应用煤与瓦斯突出综合假说,从煤层瓦斯生成、运移、储存的角度,分析研究了岩浆热液作用、地质构造、煤层埋深等因素对煤层煤质、煤层生烃能力、瓦斯含量和压力等煤层瓦斯参数及瓦斯突出因素的影响,确定岩浆热作用对瓦斯突出具有严重影响作用,地质构造、煤层埋深等因素对瓦斯突出具有中等影响作用和一般影响作用,该结论为地质勘探、矿井设计与生产规划、矿井瓦斯防治提供了理论依据.
