Rich ores have been being excavated in the course of more than 40-year-old exploitation of Streltsovskoe ore field deposits. Nowadays, the rest reserves of deposits include crude and poor ores. Physical and chemical geotechnology (method of block underground leaching) can be the prospective direction, making possible to carry out the efficient development of poor ores at the created situation. By the example of development of certain block of «Glubokiy» mine, there were carried out the calculations, which show, that during the block underground leaching, the cost price of obtaining of final products is by 30% lower in comparison with the traditional technology: horizontal layers with solid stowing with 70% of uranium extraction from the stored ore in underground leaching block.
