Abstract

Conception of geotechnology of underground leaching (UL) has been developed on the base of 50-years experience of layer-infiltration deposits of uranium development. The parameters, limited processes of underground leaching of different technologies and natural facilities has been established, qualitative and quantitative influences on efficiency of underground leaching have been defined. On the base of educed regularities the determination dynamical model of uranium underground leaching, adopted as conformity to fact results of technological blocks (cells) tests, has been developed. Efficiency is high (90%). The methods for determining the correction factors (adaptation to local conditions) was developed to apply the model to any objects of UL (Kazakhstan, Russia, Ukraine, China, etc.). Efficiency of UL is estimated by model of economical evaluation, which is a shop price of production of one kilogram of uranium, summarized with costs of essential works. The models, combined with software, allow us to solve different problems of geotechnological zoning of hydrogenic uranium deposits, design of technological preparation of UL production, development and realization of plans of mining works at enterprises with UL, education and training.
