| 摘 要： | 通过对大量钻孔数据和生产矿井实测资料的综合分析,基本探明荥巩煤田二1煤层煤层气含量呈由西向东、由浅而深逐渐增大的分布规律,按照煤层气含量变化及其地质背景的差异将煤田分为4个煤层气地质单元;认为围岩、煤层厚度、煤层埋深、地质构造是影响煤层气赋存的主要因素,其叠加效应增加了煤层气赋存的复杂性和不均衡性。据此,确定了荥巩煤田煤层气的富集带和排泄区。

| Abstract: | After synthetically analyzed large amount drilling data and measured data from active mines, basically find out the No.II-1 coal seam CBM content distributing pattern of increasing from west to east, shallow to deep in the Xinggong coalfield. Based on changes in CBM content and differences in geological setting, divided the coalfield into four CBM geological units. Considered that the surrounding rock, coal seam thickness, buried depth and geological structure are main influencing factors to CBM hosting pattern, and their superimposing effects have increased complexity and heterogeneity of CBM hosting. On these grounds, CBM bonanza and escaping zones in Xinggong coalfield confirmed. |
