| Abstract: | Methane excessive limit in upper corner angle area is a major problem during roof-coal - caving operation, when it is difficulty to lay out specialized methane discharging roadways in thinner coal seams, besides using E ventilation mode, vertical roof boreholes are used to discharge methane. In this paper, through laboratory simulation and on-the-spot test and study, reasonable parameters of boreholes and experimental effect are analyzed; its conclusion has reference and guide effect on methane prevention and control during roof-coal-caving operation. |
