ABSTRACT
The aim of this work was to evaluate the possibility of reclamation and management of mine dump material in degraded and devastated areas containing hazardous substances. In this study, we focused on the determination of changes in electrical conductivity (EC) coefficients and physicochemical parameters of mine soils for biological reclamation needs. The waste substrate material studied here showed significantly lower EC over time in tests, with a value of 6.54 dS m−1 decreased to 0.54 dS m−1. Increasing mine soil quality index corresponded with an increased concentration of exchangeable calcium ions. The cation ratio of soil structural stability indicator was positively correlated with increasing EC. Estimating the changes in physicochemical parameters of deposited reclamation material and its gradual transformation provides new knowledge that can be used for the management of mine waste for ecological purposes. In this investigation, we showed that technical activities connected with the management of opencast mining, which may involve removal of contamination from exploited areas, purification of exploited ground or pedogenesis process on waste dump, may be evaluated using the above indicators, artificial neural networks and principal component analysis.

污水污泥和矿山废弃物混合物在退化地区复垦中的评价
摘要
这项工作的目的是评估在含有有害物质的退化和破坏区域中回收和管理矿山垃圾材料的可能性。在这项研究中,我们专注于确定矿山土壤的电导率 (EC) 系数和物理化学参数的变化,以满足生物复垦的需要。此处研究的废弃基材在测试中随着时间的推移显示出显着降低的 EC,其值为 6.54 dS m -1降至 0.54 dS m -1. 提高矿山土壤质量指数与提高可交换钙离子浓度相对应。土壤结构稳定性指标的阳离子比与EC的增加呈正相关。估计沉积的复垦材料的物理化学参数的变化及其逐渐转变提供了可用于生态目的的矿山废物管理的新知识。在本次调查中,我们表明,与露天采矿管理相关的技术活动,可能涉及从开采区域清除污染、净化已开采土地或废物堆场的成土过程,可以使用上述指标、人工神经网络和主成分分析。
