FIELD: underground mining of solid minerals, preferably, low-strength ones; applicable in mining of thick coal seams. SUBSTANCE: method consists in drilling holes in deposit by auger drill with delivery of drilled out mineral to haulage drift. Drilling out is carried out at lower boundary of mined district of deposit. After drilling out of useful mineral, mineral mass overlaying the cavity formed by drilling-out is loosened, preferably by drilling and blasting without withdrawal of auger drill string. Output of loosened useful mineral from hole is accomplished by auger drill string up to appearance of cap rocks. EFFECT: extended field of application of auger drill mining and increased yield of graded useful mineral. 3 cl, 2 dwg
