FIELD: mining.
SUBSTANCE: method includes air supply from main mines along panel transport mines to block transport mines to areas of mining works and removal of spent air from bottom hole through split chambers in block ventilation mines to panel ventilation mines further to main ventilation mines, at the same time part of spent air from panel ventilation mines through blocks, where treatment works are not carried out, recirculates to block ventilation and split mines, and also through block transport mines, to panel transport mines with the help of additional recirculating ventilation plants located on panel and block mines, where mining works are not carried out.
EFFECT: lower risk of contaminated air accumulation in mined-out space, provision of stable microclimate in areas of mining works and reduced costs for ventilation.
