Term of concession contract for extraction of mineral resources – building materials – marble from “Klokotnitsa” field – 25 years

Klokotnitsa field is located about 1 km east of the village of Klokotnitsa. The mineral resources – marbles meet the requirements of BDS for crushed stone for road foundations, asphalt coatings and concrete. The terrain of the deposit, a natural hill with a slope to the east, favours to operate in an open way, at the level from above to the height of the working step water column height (head) = 15.0 m. As per necessity, are operated simultaneously several working levels. Directly from the field there are asphalt roads, used for transportation of extracted raw material to the crushing and sorting plant or to the sifting and sorting installations. Technological processes at the quarry pass successively during different stages of blasting, crushing, sifting, feeding with the extracted materials through the check grill of the receiving bunker, crushing in the jaw and cone crushers, transporting with rubber conveyor belts to separate landfills after which the materials are ready for loading and dispatching. Mining works are conducted using a classical design scheme with successive mining of deposits from top to bottom along the entire thickness of the mineral resource.
