高沼气综采工作面合理通风参数研究

Study of Reasonable Ventilation Parameter in Fully Mechanized Face with High Contents of Methane

本文分析了高沼气综采工作面沼气涌出的一般规律,沼气涌出和通风方式、煤炭产量之间的关系。提出了高沼气综采工作面沼气涌出的预测方法及合理通风参数的确定方法。最后通过实例说明该方法的应用。

This paper discusses the general law of gas emission in fully mechanized face with high contents of methane. The relationship between gas emission and ventilation patterns and that between gas emission and coal output are presented. The authors propose a method of gas emission forecast and that of determining reasonable ventilation parameters in fully mechanized face with high contents of methane. Finally, the application of these methods is explained by an example.
