Abstract
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.关键词
