Establishment of Monitoring Index system for Ecological Restoration in Open-pit Mines and Discussion on Some key Problems

Objective‌ In order to promote the ecological protection and restoration of open-pit mines, this paper constructs the monitoring index system of ecological restoration of open-pit mines.

Methods In this paper, the monitoring index, influencing factors and monitoring frequency of ecological restoration in open-pit mines are studied by means of literature study, systematic analysis, investigation, comparative study and induction, the monitoring concept of mine ecological restoration in the new era and the barriers to be solved are put forward;

Results ① the monitoring content of ecological restoration in open-pit mine includes three levels, the first level includes four aspects: basic information of mine, original ecological geological conditions, current situation of mine ecological problems, ecological restoration process of mine and monitoring of Management and protection stage, the last three first-level contents include 6 second-level contents: Hidden Danger of mine geological safety, aquifer, landform and landscape, land resources, water and soil geochemistry, damage and repair monitoring of ecosystem; ② geological environment condition, ecological system type, mining method, ecological damage degree, mine type, various restoration measures and cycle length are the factors that affect the monitoring of ecological restoration in open-pit mines; ③ the monitoring concept of ecological restoration in open-pit Mines is scientific, systematic, multi-disciplinary, comprehensive, multi-category, continuous, whole life cycle and all elements; ④ the whole-factor, whole-area and real-time transmission technology of mine ecological restoration monitoring and the monitoring of mine ecological restoration under the protection of law need to be studied deeply as an asset.

Conclusion The research results provide theoretical basis for mine ecological restoration and early warning.
