摘要
抽放半径是瓦斯抽放钻孔布置的基础参数,以阳煤集团新景矿3#煤层为背景,通过分析瓦斯抽放有效半径的测试原理及方法,采用了压降法进行试验研究,为瓦斯抽采设计提供了科学依据,从而提高瓦斯抽放的效果。
Drainage Radius is the basis of the parameters of the gas drainage drilling arrangement, In this paper, Xinjing Yang quan coal mine 3^# coal as the background,through the analysis of the test method and the principle of the drainage radius, using the voltage drop method to research, so as to provide a scientific basis for the Drainage design to improve the effect of gas drainage.
