Woody biomass-fuelled furnace:
Did you know?
Approximately 160 tons of steel and reinforcing bars were used to build the foundation and supporting structures of the straw-fuelled boiler and about the same quantity was needed for the bale storage facility. This amount would be sufficient to build about 90 detached houses.
Karolina surface mine
Karolina surface mine opened in 1968. Our Company carried out mining activity in this mine during the period between 1993 and 2004. The area of the present surface mine to be rehabilitated is an approximately 1200 m long by 600 m wide site with a surface of 120 hectare.
The mine pit left there when the surface mining activity of Pécsbánya Karolina was terminated and the land surface concerned together with the spoil banks are considered to be the base state for land rehabilitation. Our company has prepared the land rehabilitation plans with regard to urban development, landscape and environmental protection, geological, water protection and ecological requirements taking into consideration draining characteristics. As a result of the implementation of reclamation:
- an appealing landscape will be formed which will topographically fit well into the surroundings, establishing the conditions of harmony with the natural environment, connection to the urban area, natural surface water drainage and protection against erosion and in addition it endeavours easier maintenance;
- primary land rehabilitation goals on the land to be reclaimed are restoration of woods and fundamentally green area lawns. Green-belt like utilization ensures clean and fresh air supply for the city from the direction of the Mecsek forests.
Within the framework of rehabilitation the pit will be backfilled. The surface to be formed by refilling shall harmonize with the surrounding landscape with a southward-flowing stream bed. The slopes surrounding this large surface in semi-circles will be tailored with contours approximating natural formations.
According to the plans, the surface to be formed in this way shall receive a 40-centimeter topsoil and grass will be grown in the entire surface followed by afforestation in an area of almost 65 hectares.
Under a government decree the majority of the financial resources necessary for the land rehabilitation of Pécsbánya-Karolina surface mine shall be ensured by the state. Having regard to the fact that the government resources required for the land rehabilitation have hitherto not been available, the works cannot be started yet. The implementation schedule as well as the date of expected accomplishment depends on the availability of the state resources.
