摘要
By describing the design and construction of directional drilling long borehole and the effect of the gas drainage, the paper indicated that the process is stable, low cost and convenient to control, by which the gas will be extracted after been relieved by the protective layer. Compared with the other processes being used on the ground, the advantages are more prominent, the process is valuable in promotion and application. © Sila Science. All Rights Reserved.
