塔山矿瓦斯地质特征及影响因素分析

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。

Analysis of Gas Geological Features and Influence Factors in Tashan Mine

Taking the gas geology theory as the foundation,combining coal geological data with the measured gas parameter,the distribution of igneous rocks,metamorphic degree of coal,coal seam thickness,burial depth of coal seam and the overlying bedrock thickness geological factors on two geological units within the gas occurrence is carried out qualitative and quantitative analysis,the results show that volatile measure of metamorphic degree of coal is the main controlling factors of the gas content of magmatic intrusion,the burial depth and the overlying bedrock thickness are the main controlling factors which affect the gas content of magmatic rock region in coal seam.
