Abstract: The study is devoted to the issue of currently inactive metal deposit reserve introduction into production. The research of underground metal block leaching technology with the preparation according to the traditional scheme determined that the traditional preparation of PV units is ineffective. It is reasonable to carry out leaching on the basis of a solid non-pillar scheme which reduces the amount of preparatory solid works. The methods of technology development determination effectiveness by comparing the index a useful component complete extraction from the depths by the traditional and the combined method. The importance of leaching mountain aspect research is determined for the implementation of the mining production tasks.
