Usage of thermal energy contained in abandoned, flooded, coal mines has the potential to contribute low carbon heating or cooling supply and assist meeting net-zero emission targets. However, hazardous ground gases, such as CH 4 CO 2 , can be found naturally superficial deposits, bearing strata abandoned mines. Determining presence, magnitude, origin subsurface how their geochemical fingerprint...

Abstract The seasonal and spatial changes in the chemical composition of water abandoned mine drainages rivers Yudong River area years 2017–2018 were analyzed. effects drainage on seasonality physicochemical properties river after closure evaluated, feasibility irrigation using degree pollution to farmland assessed Water Quality Standard for Farmland Irrigation . results show that has low pH va...

Open-pit mining is one of the main exploiting methods for solid mineral resources. After more than 100 years high-intensity development, there are a large number abandoned open-pit mines and related relics in world. The reconstruction Pumped Hydraulic Energy Storage systems (PHES) from an effective utilization mode underground space recent years. project planning PHES should consider not only t...

The most important and sensitive level in the modification of rangelands surrounding the mine is the initial seedling establishment of plants, which often faces failure due to adverse environmental conditions, poor soil nutrients, disturbance of soil different layers and its instability and unstable soil around the mines. New methods of rangeland improvement using biological and non-biological ...

To evaluate the accumulation of trace elements (TE) by vegetables produced in the vicinity of abandoned pyrite mines, eighteen different small farms were selected near three mines from the Portuguese sector of the Iberian Pyrite Belt (São Domingos, Aljustrel and Lousal). Total and bioavailable As, Cu, Pb, and Zn concentrations were analyzed in the soils, and the same TE were analyzed in three d...
