FIELD: mining.
SUBSTANCE: method for geotechnological development of deposits includes increasing massif cracking by means of explosive tillage, supply of leaching solution into massif, changing useful component into liquid phase and lifting material to the surface. After tillage of massif, upper layer of massif rock is removed from the surface to the level of subsurface waters. Afterwards well is driven into lower part of mineralisation zone, and massif is dried through it. Hygroscopic material is laid onto surface with hydraulic insulation of its surface, and leaching solution in pumped into massif through well. After filling of massif, leaching solution supply is started proportionately to speed of liquid phase absorption by hygroscopic layer on the surface. Product solution accumulated in hygroscopic layer is removed and sent to extract useful component from it and to recover the properties of the solution itself, afterwards restored solution is again supplied into massif through well.
EFFECT: increased efficiency of deposits development.
