Underground and opencast mining adversely affects the surrounding environment. This process may continue even decades after end of actual mineral extraction. One most significant effects ceased are secondary deformations. Safe, new development post-mining areas requires reliable information on potential deformation risk zones, which be difficult to obtain due a lack necessary data. study aimed ...

The sustainable transformation of surface coal mines aims to recover geoenvironmental and socioeconomic factors (ecosystems, landscape, soil, water, employment, etc.) related extractive operations. transition sustainability starts when a mine enters the ageing/closing phase includes large-scale technical activities for repurposing mined sites. Moreover, circular economy practices methods are in...

Exploitation of lignite in continuous surface mines requires removing masses overburden, which are hauled to a dumpsite. There some technological arrangements where the overburden is transported several dozen meters down spreader operating on lower located dumping level. Depending an angle declined transportation route, there possibility convert potential gravitational energy conveyed into elec...

Aqueous phosphate uptake is needed to reduce global eutrophication. Negatively charged adsorbent surfaces usually give poor sorption. Chemically- and thermally-modified lignite (CTL) was prepared by impregnating low-cost (RL) with Ca2+ Mg2+ cations, basified KOH (pH ̴ 13.9), followed a 1 h 600 °C pyrolysis under nitrogen. CTL has positive surface (PZC = 13) due basic Ca Mg compounds, facilitatin...
