Abstract

One of the most important factors of economic development in a country or a region is ecological capital and resource potential based on mineral reserves. The latter is what crucially governs gold production level at the Navoi Mining and Metallurgical Combinat, Republic of Uzbekistan. Gold is currently mined at mostly large and medium-size deposits using the generally accepted gross method. As the reserves are being depleted, it is of the highest concern to start development of small gold deposits in the wild spaces of Kyzylkum and Nurata territories. Having analyzed the international experience gained in open pit mining of small and remote mineral deposits, this article authors propose the technology of mining with hydraulic backhoe shovels for small gold deposits of Kyzylkum. Ore loss and dilution with gangue during operation of such shovels at mixed faces (ore and gangue) are calculated. It is found that as against the widely used front acting shovels, the hydraulic backhoe machines at complex faces allow reduction in ore loss and dilution by two times and 20%, respectively.
