FIELD: mining.
SUBSTANCE: invention relates to mining industry and can be used in mining operations on placer mineral deposits using bulldozer equipment. Method of development of difficult to wash and boulder gravel deposits of minerals involves overburdening works, formation of watered trench and transportation of sands by means of bulldozer equipment to flushing equipment. At that after creation of water-flooding trench primary transportation of sand is performed by bulldozer equipment with perforated dumps in direction opposite to flushing equipment, and secondary transportation of sands to dressing equipment is performed with equipment with usual dump equipment.
EFFECT: increased efficiency of mining equipment, increased efficiency of development of high-clay sands, simultaneously containing considerable amount of boulder material, and also increased degree of useful component extraction.
