CHINA MINE ENGINEERING

Under the background of continuous promotion of ecological restoration in open-pit mine, an open-pit mine is taken as an example, this paper analyzes the existing geological environment and natural ecological environment problems, evaluation of slope stability based on geotechnical properties and soil nutrients, adopt “slope cutting flat plate+rail pile+slope toe pressing+drainage” and “anchor rod and lattice slope protection+retaining wall”, “grouting fire extinguishing+retaining wall” to implement overall and local treatment, the plan of ecological restoration in different districts should be worked out, it is of practical significance to study the measures of open pit renovation.
