Research on compression and replacement and filling control plan for internal dump in Shengli East No.2 Open-pit Coal Mine
WANG Puyi
Abstract：In order to effectively control the deformed area of the internal dump in Shengli East No.2 Open-pit Coal Mine,based on the actual conditions of the on-site engineering,the article presents a comprehensive slope control idea of"compression first and then replacement and filling",designs two local replacement and filling schemes and delineats the mining boundary according to specific parameters,comprehensively compares multiple factors to determine the optimal control scheme.The results show that the proposed control scheme one can effectively maintain the stability of the deformed area in the internal dump,maximize the recovery of coal resources,avoid economic losses caused by landslides,and ensure the normal continuation of production,transportation and other operations in open-pit coal mines.
