Evaluation and Application of Land Reclamation Suitability in Open-pit Quarry
[Objective] To construct a reasonable and feasible evaluating indicator system in order to improve decision-making for open-pit quarry reclamation modes under different conditions.[Methods] Analytic hierarchy process(AHP) was used to calculate the weights of evaluation factors under three different land reclamation modes.[Results] ① With the consideration of topographical
natural and socio-economic conditions
eight evaluation factors including slope gradient
slope roughness
vegetation coverage
average effective soil thickness
average annual precipitation
socio-economic level
distance to city center and degree of quarry aggregation were selected to establish the evaluating indicator system and criteria. ② Beishan open-pit quarry reclaimed as the Fengshanzhen National Mine Park in Jiaozuo City was analyzed as a typical example. The results verified suitability of the evaluating indicator system.[Conclusion] The evaluating indicator system and criteria can provide references for land reclamation mode of open-pit quarry of related areas.
