FIELD: mining, particularly underground mining of diamond-containing potassium salt deposits.
SUBSTANCE: method involves drilling exploratory potassium holes from surface; contouring potassium deposit, zones of sylvinite replacement with rock salt; cutting breakage and development headings with cutter-loaders; performing ground seismic prospecting by common depth point procedure in replacement zone propagation; cutting exploratory workings in rock salt laying under sylvinite seams; drilling sylvinite wells in exploratory working roofs to determine replacement zone boundaries; performing seismic investigations; exploring contoured deposits to search for diamonds; taking samples; solving taken samples in salt component; enriching the samples by thermochemical pressure decomposition, which is carried out by hydraulic jigging; determining mineable diamond zones; stoping diamond-containing salts and transporting thereof to concentrating mill.
EFFECT: increased raw material development complexity.
