Abstract： Landslide， dam break and other disasters and accidents still need to draw attention from the industry after the closure of tailings pond. One of the main ways to solve this problem is to recover and utilize tailings. In order to better recover and utilize tailings， the advantages and disadvantages of three schemes of dry mining， wet mining and combined mining were analyzed respectively， and a comparative study was carried out. At the same time， based on a practical project， the optimal combined mining scheme is selected.

Keywords： tailings pond; mining scheme; dry mining; wet mining; combined mining

有官方统计资料表明：截至2021年底，我国共有矿山3万余座，这其中既包括金属矿山也包括非金属矿山，现役尾矿库7 000余座。（剩余4014字）
