摘　　要：离子型稀土矿在生产过程中,伴随着一定的地质灾害风险,在开采前及开采期间需要进行科学防范。采用防渗深井对保护区进行地下水体的隔离保护,防止外来液体渗入保护区内造成含水过量,为科学有效地降低地质灾害提供了一种科学有效、低成本的工程技术方法。实践结果表明:井口口径φ135mm~180mm,井深大于附近注液井,孔距0.5m~1m,排距1m~3m的防渗深井工程,可以大幅降低离子型稀土矿生产过程中山体滑坡、边坡失稳、地面沉降等地质灾害风险。During the production of ion adsorption-type rare earth deposits,Some geological disaster risks may arise which need prevent.The use of anti-seepage deep wells for the isolation and protection of underground water in the protected area prevents the infiltration of liquids into the protected area,resulting in excessive water content.It provides a scientific,effective,and low-cost engineering technology method for scientifically and effectively reducing geological disasters.Practices indicate:φ135-180mm wellhead diameter,Well depth deeper than nearby injection wells,0.5m~1m Hole spacing,1m~3m hole row,The anti-seepage deep well project can significantly reduce the risk of geological disasters such as landslides,slope instability,and ground subsidence during mining.
