煤层注水快速掘进工艺对煤层气贮存效果的研究

Study on the storage effect of coalbed methane by rapid driving technology of coalbed water injection

本文通过测定瓦斯涌出初速度,论述了煤层注水可以提高煤层气在煤体里的贮存效果,同时煤层注水可以加快巷道掘进速度。通过对临时支护的模拟,证明可以在安全的前提下进行快速掘进,提高瓦斯抽采设备的上线速度,为煤层气的开采应用做了重要的前期准备工作。

This paper discusses that coal seam water injection can improve the storage effect of coal seam gas in the coal body by measuring the initial speed of gas emission. At the same time,coal seam water injection can speed up the tunneling speed of the tunnel. Through the simulation of temporary support,it is proved that the rapid excavation can be carried out on the premise of safety,and the online speed of gas extraction equipment can be improved,which makes an important advance for the exploitation and application of coal seam gas period preparation.
