FIELD: mining.
SUBSTANCE: invention relates to mining and can be used in development of mineral deposits represented by steeply dipping ore bodies or bodies of high thickness, where application of traditional methods is considerably complicated by mining and geological conditions. Method of combined development of mineral deposits involves drilling of descending wells from the surface, identification of productive sections, some of which are penetrated by descending wells from the surface. Equipment for borehole hydraulic production is placed in wells and hydraulic washing of rocks is performed. Pulp is lifted to the surface. Driving of vertical or inclined shaft in side rocks, opening inclined workings from shaft to ore body with inclination towards shaft and opening working for creation of artificial ceiling in unproductive section above massif of ore body, developed from underground opening workings. Said massif is mined. In the opening inclined workings receiving chambers are created, in front of which preliminary dressing means are installed. From the opening inclined workings there are inclined development workings with an inclination towards the opening workings, from the opening inclined and development workings into the productive sections lying below the artificial ceiling, ascending wells are drilled, in which equipment for well hydraulic production is placed and hydraulic erosion is performed from top to bottom with gravity delivery of the obtained pulp through wells, development workings and opening inclined workings to means of preliminary dressing, on which coarse fractions are separated from pulp and then delivered to receiving chambers, from which pulp is lifted to the surface. Mineral is extracted from the separated coarse fractions.
EFFECT: avoiding losses of the largest and most valuable crystals or nuggets, considerable reduction of energy consumption for extraction.
