Nowadays the majority of deposits are successfully exploiting by mining enterprises with the help of traditional excavation and loading equipment. Typically, metals, construction materials, etc. are mined and extracted on these deposits, but modern society is progressing and producing new requirements to metals properties for creating a new type of equipment. The metals with new properties are located in unconventional areas: either in technogenic deposits (overburden dumps, tailings, etc.) or in hard-to-get natural formations. Technogenic mines, being a tailing of Kachkanarsky mining and processing plant, are referred to such unique deposits, which have expensive metals (scandium, gallium, strontium, titanium), as well as the natural deposit – rhenium deposit, located in the crater of an active volcano. Potentialities of open mining in the largest rhenium deposit with complex environmental occurrence have been analyzed in the paper. Temperature measurement results of adjacent strata and a temperature scheme of the host rocks on a separate site and the entire field have been presented. An open mining technique for a primary mining area as well as perspective methods of rock preparation for excavation, applicable to this particular deposit, has been considered.
In work it is settled an invoice the final depth of a pit of the conditional complex occurrence presented by three minerals. It is shown that when developing complex occurrence it is more expedient to use coefficient of output, instead of overburden ratio.
The paper considers the advantages and disadvantages of technological options for the training of new horizons in the fields of mineral resources with large water production using excavators such as direct and backhoes.
The work evaluated the impact of the bench height on the development of mining operations and quarry capacity of ore. The analysis of the height of the step depends on the area of the ore deposit within the quarry field, as well as the dependence of the length of the scope of work on the angle of the ore body.
New approaches to the design of low-waste opencast mining of complex mineral deposits using modern mining efficiency criteria in determining the main parameters of a opencast. The main technological and environmental characteristics flow of ore technological requirements for opencast mining environment of the Ozerny polymetallic deposit, located near specially protected zone of lake Baikal.
