综掘工作面瓦斯煤尘的治理

To bring gas and coal dust under control in full-heading face

在瓦斯含量较大的煤层采用综掘掘进巷道，由于掘进速度快，出现了瓦斯涌出量过大的现象。虽然采取了许多通风方法，但是都不能彻底治理综掘工作面的瓦斯、煤尘。现提出采用调压通风方法治理综掘工作面的瓦斯、煤尘，并取得较好的效果。

Under gassy coal seam condition, the full-heading development is employed. Because of the fast heading a high rate of gas emission arises. Many ventilation methods have adopted, but no one could bring gas and coal dust under control entirely. This paper put forward the method as adjusting-pressure ventilation and a better result made for the work mentioned above was introduced.
