摘要：
The mining-and-geological conditions are analyzed for the occurrence conditions of gold placers, where the hydraulic borehole mining is expedient. The empirical dependences are established for calculating the basic parameters of hydraulic mining through the boreholes drilled in carrying out the experimental-industrial tests. The prototypes of hydraulic mining equipment are designed and tested. The trends are determined for the increase in efficiency of hydraulic borehole mining from thawed and frozen placers of different thickness.
