METHOD FOR LAND RECLAMATION IN THE CASE OF LAND CORRUPTION BY OPENED DEPOSIT DEVELOPMENT

FIELD: mining, particularly reclamation of surface-mined areas in agriculture and building industry. ^ SUBSTANCE: method involves selectively excavating, moving and accumulating ground layer and overburden in separate strip dumps; excavating open-pit field; filling and smoothing thereof and ground layer laying. After open-pit field excavation the excavated space is filled with building waste up to high ground water layer. The building waste has composition close to that of natural minerals with different fraction dimensions. The building waste is laid in several layers each having thickness of 40-60 cm. Each layer is compacted with soil compactors or compacting mechanism. Then draining layer is laid. The draining layer has particle dimensions of 150-200 mm and thickness of not less than 0.6 m. The draining layer is compacted by vibratory plates. Draining layer is covered with fertile ground so that fertile ground layer having thickness of not less than 0.3 m is created. Then straw layer in which chemical fertilizers and perennial grass seeds are added is formed over fertile ground layer. The straw layer is smoothed and sprinkled with dispersions containing water-soluble polymeric substances and synthetic water-soluble phosphates, wherein synthetic water-soluble phosphates are taken in amount of 1-4% by ready dispersion weight. ^ EFFECT: reduced labor inputs and reclamation work costs, improved land protection against wind erosion and scouring. ^ 4 cl, 1 dwg
