| Abstract: | In the two-step continuous mining process of Dahongshan Copper Mine,cemented pillars will replace primary pillars to serve the mining of adjacent mine houses.In order to ensure the safety of the two-step mining process,it is necessary to study and analyze the stability of cemented pillars.Taking the B12-20 line mining area in the middle section of 385 as the research object,the numerical simulation research is carried out by FLAC3D software.The results show that the cemented pillar in the B12-20 line mining area in the middle section of 385 can ensure its own stability without instability and damage,thus providing a safe and reliable working environment for mining in the section. |
