In underdeveloped areas of Kazakhstan, several thousand small gold and rare-metal deposits are located at a depth inaccessible for open mining, which in their limited reserves are either classified as off-balance or are not included in the register of reserves of the SCR (state Committee of reserves). This article discusses the creation and development of new technologies that are based on the use of fundamentally new technical means will be effective and able to reduce the cost of mining. The hydro impulse method of destruction of rocks of any fortress is offered that will allow reducing sharply volumes of capital and operational works at a considerable decrease in their Prime cost. Therefore, it will be possible to involve in the effective development of numerous off-balance gold and rare-metal deposits of Kazakhstan. For this purpose, a comparative analysis of the economic and technical efficiency of the hydro-pulse destruction of strong and abrasive rocks in the ore industry with respect to the existing drilling and blasting technology is given, the developed design of an environmentally friendly electric-discharge hydro-pulse gun GPE-1200 with a very high power of hydrofoil is described. The specific recommended design mechanisms, shut-off valves water gun, operating at ultrahigh hydrostatic inside aggregate pressures, which include how to combine the blasting of the rock mass in the excavation or clearing works and use the device for drilling wells.
