摘要
针对目前采煤工作面瓦斯来源分析方法的不足,基于工作面横断面上瓦斯浓度变化可反映各瓦斯涌出来源的涌出情况,介绍了一种采煤工作面瓦斯分源测定技术。现场的应用实践表明:该方法操作简单,能准确地确定出主要瓦斯涌出源,为有选择性地采取措施,遏制重点源头的瓦斯涌出提供依据。
Aiming at the shortcoming of analytical method of mining coal working face gas source, because of gas thickness change of the working face cross section can reflect the source of gas Emission condition. it in？troduces one kind of the technology of coal mining working face mashgas of separated source determination. The practical application shows that the method is simple and easy to operate. It will accurately determine the main gas emission source, provide a basis for selectively taking measures to curb the key source of gas emission.
