分源预测法在整合矿井瓦斯涌出量预测的应用

Gas Emission Prediction in Integration Coal Mine Based on Different-source Prediction

瓦斯涌出量是整合矿井设计中的一个重要参数,介绍了用于瓦斯涌出量预测的分源预测法的技术原理。结合山西某整合矿井实际和生产设计,分析了地勘时钻孔瓦斯含量,利用线性回归方法研究获得了9#、10#1、1#煤层瓦斯含量与埋藏深度的关系,得出各煤层可燃质瓦斯含量增长梯度。运用分源预测法对矿井开采前期、中期和后期瓦斯涌出量进行了预测,并分析了矿井瓦斯涌出影响因素和涌出来源。研究结果对于矿井通风设计和瓦斯管理具有重要的意义。

Gas emission is important parameter in the design of integrated coal mine,the sub-source technical principles was described.With the actual mine and production design,gas content of geological exploration drilling was analysed,the relationship of gas content of the ninth,tenth and eleventh coal seam was studied by using the linear regression method,the coal seam gas content growth of flammable gradient was obtained.The early,middle and late gas emission of coal mine was predicted based on different-source prediction,the factors and emission sources were analysed.The study results were of great significance for mine ventilation and gas management.
