Abstract
Coal bumps pose a significant threat to the safe operation of coal mines. This study examines the coal bumps incident at Tangshan Mine, focusing on the influences of various disaster-causing factors, including structural stress, rock mass impact tendencies, and support and bearing capacity. To facilitate the safe resumption of production at the 0250 working face, coal seam blasting and borehole pressure relief drilling were conducted to dissipate the accumulated elastic energy within the coal seam, thereby effectively mitigating the risk of bursting. Concurrently, the vibration and displacement of the roof were monitored. The relevant monitoring data indicate that roof activity remains within a controllable range, suggesting a relatively low likelihood of coal bump incidents.
