Abstract As the throat of mine coal lifting transportation, coal bunker is an important part of coal transportation and lifting. In order to strengthen the safety management of coal bunker in coal mine, prevent and reduce the occurrence of blockage accident caused by coal bunker wall spalling and slag slipping, and ensure the safe and efficient production of coal mine. In this paper, the reinforcement technology of the bottom coal bunker of Dongpang Mine is analyzed by using the anti-impact and strong wear-resistant manganese steel plate. By applying the anti-impact and strong wear-resistant manganese steel plate reinforcement wall support technology to the reinforcement of the coal bunker wall, the strength of the coal bunker wall itself and the surrounding rock body is improved, so that the coal bunker wall forms a bearing structure, thus achieving the expected effect.
