The areas above seams normally are (or used to be) of agricultural type (mostly low-quality soil, class V or VI), often wasteland. Each seam is mined gradually and each section thereof remains unaffected until the commencement of works in its very area. Upon initiating the extraction of new resources, the depleted areas of the seam are being simultaneously recultivated. No permanent buildings are constructed within the mining area.
In the first stage of operation, the soil layer is collected and stored separately thanks to which it may be reused for biological restoration. The remaining part of overburden and part of spoil without any economic value are returned to the excavated part of the seam or collected temporarily in stockpiles in order to be used subsequently for technical recultivation purposes.
The recultivationpurpose depends on local hydrogeological conditions. In case of water-bearing seams, basins filled naturally with water are created, whereas in dry mining areas forests are grown, or they are used for agricultural purposes. The stage of technical recultivation mainly features the shallowing (reservoir) and appropriate modelling of its slopes (shores), as well as rearrangement of the rest of the former pit area. For this purpose, previously collected earth masses are moved and planted. In the final stage, separately stockpiled soil is distributed in order stimulate the vegetation of plants. The biological stage depends on local conditions and features mainly planting of pine, birch and willow trees on the shores of the reservoir or the entire area. Plant succession may be partially or completely natural.
Grounds prepared in such manner are then submitted for further administration by third parties (National Forests, local authorities, private owners). Usage of pit areas for broadly understood leisure (tourism, sports) purposes is a worthwhile land development concept. Fish farms and agrotourism facilities are established on recultivated reservoirs. On the other hand, dry pits only after necessary remodelling may be used for various sports activity (cross country running, ski running, cycling or motorcycle sports), however such projects in reality are still of a rather prospective character. As we operate also in protected natural zones, one of the main goals of recultivation is simply returning of land to nature.
It is worth noting that all the above described restoration works are performed with our own funds gathered on a dedicated account during the entire mining period. They may be used exclusively for the purpose of recultivation. The recultivation purpose is always agreed with local authorities who also perform the acceptance of performed works.
