METHOD OF DEVELOPMENT OF SOLID MINERAL DEPOSITS

摘要

FIELD: mining and mining-and-smelting industries. SUBSTANCE: method includes separation of mined and barren rock blocks in worked bench or zone; loosening of rocks comprising blocks by blasting of horizontal borehole charges of small or medium-size diameter under mobile shelter; rapid assay of mineral; differentiation of mined block into extraction members by number of main parameters of mineral quality; said members selective extraction; mineral treatment and processing of standard quality mineral mass. EFFECT: higher efficiency of opencast mining of solid mineral deposits due to reduced capital and working costs. 4 cl, 1 dwg
