Goaf Gas Control Improvement by Optimizing the Adjacent Roadway Large-Diameter Boreholes
This study introduced gas control technology in goaf using adjacent roadway large-diameter (550 mm) boreholes to control gas accumulation in the upper corner of a fully mechanized working face in high-gas coal seams. The gas control process in the upper corner and gas interception in goaf by large-d...
