Open mining technique for unconventional mineral deposits

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.

Use of coefficient of output at pit delimitation

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.

Quarry capacity of ore relation from bench height

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.
