摘　　要： 为了研究厚煤层综掘巷道煤壁瓦斯涌出规律,确定合理通风设计和完善瓦斯防治措施,运用矿井瓦斯分源预测法对厚煤层综掘巷道进行预测,同时选择相同地点实测瓦斯涌出量,通过数据分析和理论研究得出分源预测法的误差来源。研究发现巷道断面内暴露煤壁面周长与煤层厚度呈一次函数关系,并提出煤壁瓦斯涌出量预测修正系数及公式。 In order to research gas emission laws of coal wall in fully mechanized roadway of thick seam, to determine reasonable venti- lation design and make gas prevention and control measures perfect, the sub - source prediction method is used to forecast the thick seam fully mechanized roadway. Seleting same place to measure gas emission, the error sources of sub - source prediction is achieved by data analysis and theoretical research. The study show that coal wall perimeter exposed to the roadway section is a function relation with the thickness of coal seam. Finally, the paper puts forward the correction coefficient and formula of gas emission prediction;gas e- mission law.
