FIELD: mining industry; mining of thick flat deposits of valuable and medium value ores of low hardness. SUBSTANCE: method includes working of chambers in panels by vertical cylindrical holes of large diameter with gravitation delivery of ore. Chambers in panel are worked in two stages with subsequent filling of them with fill material. Holes are drilled with spacing equal to 2/3 of their diameter. EFFECT: highly efficient continuous technology of ore mining with high coefficient of ore recovery. 2 dwg
