环境安全与资源的桃战和机遇——煤层甲烷

COAL-SEAM METHANE:ENVIRONMENT,SAFETY AND RESOURCES

甲烷是强烈的温室气体 ,煤层甲烷是煤矿瓦斯灾害之源 ,也是洁净的能源。综合采用井下现场测定、矿山统计分析和实验室试验确定的煤层瓦斯参数可靠性高 ,首次提出的含量法预测矿井瓦斯涌出量理论模型和邻近层瓦斯涌出率曲线 ,预测精度高 ,适用范围广。建立了双重孔隙、可压密煤层瓦斯储运方程和数值模拟方法 ,解吸时间控制吸附瓦斯的涌出。

The coal seam methane is a source of coal mine gas calamity,and also a clear energy resources.Determinating of coal seam gas parameters by field detecting,mine statistical analysis and laboratory test is high reliable.A theorical model and adjacend seam gas discharge curve for predicting the mine gas discharge are provided.They have high prediction precision and wide applications.The compressiable seam gas storage transport equation and numerical simulation are presented.The trend of theorical research on coal seam methane is prospected.
