FIELD: mining industry; applicable in mining of ores, hard fuel minerals, precious stones, building rocks and some other hard minerals. SUBSTANCE: method of mining of hard mineral deposits is realized by means of single technological complex including stage differentiation of rock mass by key criteria, loosening of rocks by blasting of horizontal holes under mobile shield with preservation of initial geomorphologic structure of mass of mined block, successive selective excavation working of blasted blocks and separate initial processing of mined mineral. EFFECT: higher efficiency of mining of hard mineral deposits (with use of rock loosening by blasting) by reduced capital and working costs and terms of construction of concentrating mills, higher completeness of recovery of minerals from deposits and useful components from mind mineral materials.
