Introduction Complex mineral mining leads to critical earth’s surface disturbance and environmental pollution from industrial waste. This research aims comprehensively study, assess show the current scale of disturbances in largest region Ukraine – Kryvyi Rih. Iron-ore Basin suggests ways improve situation based on backfill technologies for rehabilitation waste utilization. Methods To identify forms disturbance, their parameters, spatial location, satellite images region, government statistical data, a geographic information system software suite were studied. An analysis effectiveness existing reclamation measures technogenic voids was carried out, new concept restoration proposed using beneficiation tailings, which are difficult utilize region. Results It has been determined that contribution Rih generation is 92.08% total volume accumulations Dnipropetrovsk Oblast 65.5% as whole, amounting 10.7 billion tons. 65.25% disturbed land area waste, 34.76% quarry cavities mine failure zones, occupying 49% city area. accumulation density allotted areas shows per 1 m 2 area, average, 183.5 tons dump rocks 73.5 tailings placed. Disposal recognized priority, because utilization slower, occupy creating risk dams breaching intense dusting surface, threatening environment public health. For first time Ukraine, various purposes developed paste technologies. Discussion Paste technology implementation prioritized central northern parts city, can dispose at least 65–70 million reclaim about 200 ha land. The results valuable development strategies or programs overcome technogenic-ecological crisis city. rehabilitated be usefully involved infrastructure projects economic potential an such

Three coal-based solid wastes—fly ash (FA), gasification slag (GS), and coal gangue (CG)—were used to prepare functional soil (FGC) for the ecological restoration of mining areas. It not only solves problem shortage resources in area, but also realizes resourceful use waste. Investigating physicochemical properties oatgrass growth characteristics revealed optimal ratios. Compared with control (CK) at 30 d, average pH FGC3 (FA: 50wt%; GS: 25wt%; CG: 25wt%) decreased from 9.54 8.54, organic matter content increased 2.57% 7.60%, available potassium ammonium nitrogen 38.02 2.83 mg⋅kg −1 53.46 3.21 , respectively. Functional bulk density porosity were superior Sandy somewhere Ningxia (SL) GS CG contents <25wt%. significantly improved agronomic traits. CK plant height, stem thickness, fresh weight, dry weight 17.68 cm, 0.99 mm, 0.09 g, 0.02 g 27.0 1.26 0.24 0.04 And chlorophyll was by 20.39% compared CK. This study verified feasibility synergistic preparation soils three wastes provides reference large-scale utilization wastes.

Widespread uranium mining resulted in large amounts of radioactive wastes. While impoundment has been commonly used to store U-laden wastes, information lacking on the secondary contamination potential. We conducted a field-scale study at prototype mine tailings site China understand abnormally high concentrations (0.90-36.7 μg/L) recently observed downstream groundwater. Based on-site hydrogeological measurements and modeling analysis, fracture channels were identified aquifer. To consider fissure channeling flow solute transport modeling, modified discrete-continuum coupled approach was established, which considers dynamics within both matrix domain preferential through main fractures. The model not only able simulate various locations, but also reveal U release rate from impoundment. Moreover, contaminant supported that abnormal attributed aquifer fractures, confirmed geological analysis. In addition valuable field data, this work offered an effective for assessing associated environmental impact waste disposal facilities complex settings.
