通过对不同赋存类型的离子型稀土矿山开展现场调查,论述了原地浸矿采场滑坡的基本特征和致灾机理,结合某滑坡易发稀土矿区开采技术条件,实施了滑坡防控工业对比试验。研究表明,离子型稀土矿采场滑坡的主要破坏类型为浅层小型圆弧强风化残积层滑坡,通过调整注液参数、增加收液工程、预留保安矿体、抗滑桩人工加固等防控技术措施,采场滑坡现象得到了有效控制,所用防控措施具有投入少、产出大、施工简单、效果明显等优点,可为南方离子型稀土矿山的采场防控和安全开采提供参考,解决稀土矿山面临的安全环保等现实问题,具有良好的经济和环境效益。
Based on the field investigation of ion-type rare-earth mines with different types of occurrences, the basic characteristics and mechanism of landslides in situ leaching mining stope are discussed. Combining with the mining technology conditions in a rare earth-prone mining area, landslide prevention and control industry is implemented test. The research shows that the main failure type of landslide in ionized rare earth mining is shallow shallow circular arc weathered residual landslide. By adjusting the injection parameters, increasing the liquid receiving project, reserving the security ore body and anti-slide pile artificial reinforcement Control measures and stope landslides have been effectively controlled. The control measures used are less investment, large output, simple construction and obvious effect, etc., which can provide reference for the prevention and control of safe mining of stope in the ionized rare earth mine in southern China. , To solve the practical problems of safety and environmental protection faced by rare earth mines, and has good economic and environmental benefits.
