ABSTRACT

Mined Land Suitability Assessment (MLSA) is a critical step in mine reclamation planning for ensuring the sustainability of Post-Mining Land-Use (PMLU). In this study, a general semi-quantitative MLSA approach based on the 2D assessment matrix is developed to calculate the mined land suitability score and determine the suitability level. To this end, a new PMLU classification is suggested. The proposed approach is verified in a real case, and the results’ reliability is confirmed by considering this mine’s characteristics. This new approach will facilitate choosing the suitable PMLU with high accuracy due to the assurance of mined land’s suitability.

摘要

采矿土地适宜性评估 (MLSA) 是矿山复垦规划的关键步骤，可确保采矿后土地利用 (PMLU) 的可持续性。在本研究中，开发了一种基于二维评估矩阵的通用半定量 MLSA 方法来计算开采土地的适宜性评分并确定适宜性水平。为此，建议采用新的 PMLU 分类。所提方法在实际案例中得到验证，并结合该矿的特点验证了结果的可靠性。由于保证了矿区的适宜性，这种新方法将有助于以高精度选择合适的 PMLU。
