On the analysis of gas control effect in pre-drainage roadways of belt seams in Zhaozhuang Mine by layer-through borehole, the paper verified the feasibility of covering gateway excavation with gas control. In addition, horizon selection, borehole layout, and sealing process in the process of gas drainage of layer-through borehole are illustrated, which could provide technological support and safety insurance for efficient and safe production.
