Research on the prevention and manage of rockburst in deep‐seam mining roadways
Energy Science & EngineeringAbstractThis study presents a strategy for preventing and controlling rockbursts in deep and vast seams during the mining operation. We analyzed the main factors influencing rockburst by combining the geological structure of the rock mass with field‐collected microseismic monitoring data.
