| 摘 要： | 根据实测金地井田8#、13#煤层瓦斯含量和气体组分实验室测定结果,结合金地井田的地质构造特征及煤层瓦斯垂直分带理论,分析认为:金地井田范围内8#、13#煤层均处于瓦斯风化带。同时应用分源预测法对金地井田不同生产时期的回采工作面瓦斯涌出量含量进行了预测。

| Abstract: | According to the field measurement of No.8 and No.13 coal seam gas content in Jindi coal field and the laboratory measuring results of gas component,combining with the geological structure characteristics of Jindi coal field and gas vertical zonation theory,the analyzing result shows that the No.8 and No.13 coal seams of Jindi coal field are located in gas weathering zone.The paper also predicted the gas emission of the working faces in the different production times by using the different-source forecast method. |
