METHOD FOR EXTRACTION OF HARD MINERAL RESOURCES FROM DEEP-LYING WATER-FLOODED DEPOSIT

摘要

FIELD: mining.;SUBSTANCE: method for extraction of hard mineral resources from deep-lying water-flooded deposit consists in open-pit field drilling by rows of multi-functional wells oriented in a certain way that are used for down-hole hydraulic mining of mineral in the period of overburden operations at dry-excavated pit, as well as for supplementary exploration of mine field, parameters monitoring and drying of rocks.;EFFECT: increase of efficiency of traditional methods for mine fields development via geo-technological methods.;1 ex, 1 tbl, 2 dwg
