研究煤层瓦斯含量的分布规律,是准确预测瓦斯涌出量和煤与瓦斯突出的重要前提。以龙滩煤矿地质勘探期间瓦斯地质资料和现场实测瓦斯数据为依据,定性、定量的分析了煤层埋藏深度、顶(底)板泥岩厚度、地质构造、煤层厚度等因素对煤层瓦斯含量的控制作用。结果表明:煤层埋藏深度是K1煤层瓦斯含量分布的主控因素,地质构造则是造成煤层瓦斯局部富集的主要原因。
Studying the distribution of gas content in coal seams is an important prerequisite for accurately predicting gas emission and coal and gas outburst. Based on the gas geological data and on-site measured gas data during the geological exploration in Longtan Coal Mine, qualitative and quantitative analysis of the control effect of coal seam gas content on factors such as coal seam burial depth, top (bottom) plate mudstone thickness, geological structure and coal seam thickness . The results show that: the depth of coal seam burial is the main controlling factor of the gas content distribution in K1 coal seam, and the geological structure is the main reason for local gas enrichment in coal seam.
