FIELD: oil and gas industry.
SUBSTANCE: invention refers to development of mineral deposits, particularly clay placers, and can be implemented in mining industry. The method consists in striking developed placers, in their layer-specific excavation with parallel trenches leaving between-trenches massifs, in concentrating and in piling. Also between the first trench and the circuit of developed deposit an additional ditch is made, wherein water is supplied; when a successive trench is entered, each preceding trench is successively filled with water. When the last trench is driven, deposit is flooded; between trenches massifs are debugged by means of a drag or dredger; notably, debugging is performed from the first trench to the last one.
EFFECT: increased efficiency of clay placers development by means of increased degree of disintegration and extraction of valuable component at reduced technological losses.
