To address the issue of high gas emissions in mining gassy coal seams in underground coal mines, the concept of a three-entry panel layout with a retained goaf-edge gateroad and a “Y” type ventilation system is introduced in this paper. With the layout and ventilation system, distribution characteristics of methane concentration in the panel goaf is analyzed, technologies of gas drainage with boreholes drilled from the retained goaf-edge gateroad and into stress-relieved overlying and underlying seams are described, and an application case of such layout in a coal mine is also presented in this paper.
