Abstract

To ensure the safety of constructing large coal bunkers above the goaf of coal mines, the probability integral method was used to predict the residual settlement deformation of the ground surface, and the foundation stability of the newly built large coal bunkers was evaluated. The evaluation concluded that the new coal bunkers would cause the further activation of the goaf, and necessary safety protection technical measures should be taken for the new coal bunkers. According to the structural type of coal bunker, the specific safety monitoring methods, anti-deformation technical measures, and maintenance and reinforcement measures were proposed, providing the technical guarantee for the safe and stable operation and use of coal bunker in the future.
