Abstract Based on the engineering geology survey of the area with critical sliding rock blocks in the south open pit slope at a lead-zinc mine，the stability analysis on the sliding blocks is carried out by the 3-dimensional wedge vector analysis method. Accordingly，the reinforcement measures，such as long pre-stressed cable bolting，concrete stopping wall and water control，are taken. Through monitoring for several years and mining operation，especially in rain season，it is proved that the control and treatment for the slope are successful.
