以瓦斯地质理论为基础,结合煤田地质资料和实测瓦斯参数,定性、定量分析了岩浆岩分布状况、煤变质程度、煤层厚度、煤层埋深及上覆基岩厚度等地质因素对2个地质单元内瓦斯赋存的影响,结果表明,衡量煤变质程度的挥发分是岩浆岩侵入区瓦斯含量的主控因素,煤层埋藏深度及上覆基岩厚度是影响无岩浆岩区煤层瓦斯含量的主控因素。
Based on gas geological theory and geological data of coalfield and measured gas parameters, qualitative and quantitative analysis of the distribution of magmatic rocks, coal metamorphism degree, coal seam thickness, coal seam depth and overlying bedrock thickness and other geological factors on two geological units The results show that the volatility of coal metamorphism is the main controlling factor of gas content in the intrusion area of magmatic rocks. The depth of coal seam and the thickness of overlying bedrock are the main controlling factors affecting the gas content of coal seam in non-magmatic rock area factor.
