摘要
FIELD: mining industry.;SUBSTANCE: method includes loading of pit edge with inner dump, underground extraction of mineral resource with destructive systems, forced destruction of ceiling rock formations and filling of extracted space by formations from inner dump rocks and formations from destructed ceiling. Inner dump is formed in levels, level height is limited with, for example, transporting bench, while slant of upper level area is limited with, for example, transport bench, while slant of upper level area is taken as equal to bench slant, bench is transferred to outer edge of dump and onto upper area of first level second level is dumped, upper area of which is combined with bench, for example, transporting, operations for dumping second and following levels are repeated as during first level operations, for forced destruction of ceiling rock formations wells are drilled from bench combined to upper area of last level adjacent to it.;EFFECT: lower time and resources costs, higher safety, stable pit edge state.;3 dwg, 1 ex
