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.

Substantiation of the possibility of involvement in processing of the iron-containing tails with the subsequent clotting of the obtained concentrates

The tailings dumps of the ironore mining-reprocessing enterprises exert extremely negative influence on the environment, but at the same time, under the conditions of the impoverishment of iron ores they are potential raw source. In connection with this, a question of involvement in processing of the tails containing iron is extremely urgent. In the article the technology on processing of the waste of the beneficiation of iron ores is suggest. In this case the clotting of the obtained concentrates can be carry out by briquetting. In the work are also given the results of researches of the iron-containing tails concentrating and briquettability of the concentrates obtained of them.

Rationale for the development of the method of existing iron typetailing gully

In the Russian Federation, about 40 % of tailings dumps are in operation GOK. The development of mechanized impossible, due to heavy water production, the  stability of the dam breach and the possibility of a  breakthrough. In this regard, the task of developing the existing tailings dumps will now increase the competitiveness of enterprises and reduce the cost of iron ore concentrate.

Determining the mine working height for the development of tailing dumps hydraulic excavator backdigger

Development water sated tailing dump are accompanied explosive failure banks  even  at their height less 10 meters. Thereupon, the problem decision on research competence a slope and to a choice of optimum height production a dredge face «backdigger», established on the  top  platform  tailing dump, will allow to reduce equipment downtimes and to increase intensity mining.
