“…Формирането им се дължи на биологично и химично окисление на сулфидни минерали (пирит, халкопирит, сфалерит, галенит, арсенопирит) при контакт на рудна маса, въглища с високо съдържание на пиритна сяра и минерални отпадъци с въздух и вода (Luther, 1987;Acharya and Kharel, 2020). Протичането на вторични реакции като разтваряне на карбонатни и окисни минерали, неутрализация и йонен обмен води до вариране на състава на КРВ от такива с висока киселинност и съдържание на Fe, Mn, Al, As, цветни метали (Cu, Zn, Cd, Co, Ni) и сулфати до слабо кисели и неутрални води, съдържащи ниски концентрации желязо, наличие на цветни метали и високо сулфатно съдържание (Sheoran and Sheoran, 2006;Brown, 2010;Cravotta, 2010;Wang et al, 2021).…”

The formation of acid mine drainage (AMD) is a serious environmental problem in areas with mining and processing industries worldwide. Their generation is associated with chemical and biological processes of oxidation of sulfide minerals, mainly pyrite. Sources of AMD can be deposits of sulfide minerals and coal with a high content of pyrite sulfur, mining waste and some tailings. The impact of AMD on surface and groundwater in mining areas continues for decades after the cessation of extraction. An example of the negative impact of generated acid mine drainage on the state of surface waters is in the region of Madzharovo. Years after the cessation of mining, the waters at the discharge points "Momina Skala", "Harman Kaya" and "Pandak Dere" are characterized by low pH values and high concentrations of iron, copper, zinc, cadmium, lead and manganese.

“…The results showed that the metals were reduced but that the effectiveness of the treatment system declined with time, possibly due to clogging. Cravotta ( 2010 ) also studied limestone treatment in a variety of passive and semi-passive treatment systems to reduce the transport of heavy metals and to neutralise AMD in Pennsylvania. The results indicated that the wetlands effectively reduced the transport of metals as well as the acidity load.…”

A large number of filter materials, organic and inorganic, for removal of heavy metals in mine drainage have been reviewed. Bark, chitin, chitosan, commercial ion exchangers, dairy manure compost, lignite, peat, rice husks, vegetal compost, and yeast are examples of organic materials, while bio-carbons, calcareous shale, dolomite, fly ash, limestone, olivine, steel slag materials and zeolites are examples of inorganic materials. The majority of these filter materials have been investigated in laboratory studies, based on various experimental set-ups (batch and/or column tests) and different conditions. A few materials, for instance steel slag materials, have also been subjects to field investigations under real-life conditions. The results from these investigations show that steel slag materials have the potential to remove heavy metals under different conditions. Ion exchange has been suggested as the major metal removal mechanisms not only for steel slag but also for lignite. Other suggested removal mechanisms have also been identified. Adsorption has been suggested important for activated carbon, precipitation for chitosan and sulphate reduction for olivine. General findings indicate that the results with regard to metal removal vary due to experimental set ups, composition of mine drainage and properties of filter materials and the discrepancies between studies renders normalisation of data difficult. However, the literature reveals that Fe, Zn, Pb, Hg and Al are removed to a large extent. Further investigations, especially under real-life conditions, are however necessary in order to find suitable filter materials for treatment of mine drainage.

“…Generally, the environmental improvement and ecological reconstruction has been restricted to the limited water area after the management of the subsidence land. 3–9 Yet, due to the constraint of stable time, water quality and other factors, the existing approach to manage subsidence water area is not satisfactory, so are the application and profits. A series of problems exist as follows.…”

As for unilateral utilization pattern and less effective treatment of mining subsidence water area, this research proposed a construction of a floating town in subsidence water area by exploring construction land. The planning layout and spatial model of the town were designed with the aid of three-dimensional digital simulation. In the proposed design scheme, the floating module consists of superstructure, floating foundation and mooring structures. The unit module was assembled into a floating organic system as required. Such approaches, in order to realize the ecological livable ‘beautiful China’ (ecological and sustainable country), try to propose a new idea to satisfy the contradiction between population growth and demand for land, and to minimize the use of arable land and preservation of the natural environment, as well as the expansion of construction land on green field sites and the promotion of new type urbanization.
