Abstract RU 2140542 C1

FIELD: mining industry; applicable in mining of bedded mineral deposits. SUBSTANCE: method includes driving of chambers in barren rocks with stowing of broken rock into worked out spaces on commercial beds. Extraction and filling jobs are carried out simultaneously by the same mining complex including combined, two self-propelled cars, transfer bin and belt conveyor. Barren rocks are mined by large chambers on horizon located below the mined commercial bed at distance excluding geochemical connection between them. EFFECT: reduced capital and working costs, higher reliability of taken measures of protection of surface objects due to reduction of terms of lagging of stowing jobs from stopping ones. 1 dwg
