The contract is for the purchase and delivery of brand new (not older than produced in 2016) trucks, vehicles, passenger and commercial vehicles and other transport equipment for PGNiG SA Branch in Zielona Gra and PGNiG SA Branch Borehole Mining
Rescue Station in Krakow.
Its functioning draws upon the usage of brand new contemporary means of investigation, among which the following ones can be emphasized as being the most important ones: special technologies of areal dust suppression, protection of underground waters from pollutions, new technologies of hydraulic borehole mining
of high-grade iron ores and other technologies, confirmed by patents, complex of methods that uses GIS technologies (pixilated three-dimensional evaluation of mosaic vegetation mantle of spoil heaps), empirical selection of plants, characterized by man-impact tolerance, multivariate statistics, which help visualize the differences in vegetation mantle's formation, as well as to isolate statistical factors that limit its development.
Uranium ore is mined in several ways: by open pit, underground, in-situ leaching, and borehole mining
. Low-grade uranium ore mined typically contains 0.01 to 0.25% uranium oxides.
Selection of technological parameters in borehole mining
production by technical deep drilling and hydroexploitation.
Sydney, Australia, Feb 13, 2012 - (ABN Newswire) - Black Range Minerals Limited (ASX:BLR) recently engaged Kinley Exploration LLC (Kinley) in Kansas, USA, to complete a detailed preliminary technical and economic evaluation of mining the Hansen Uranium Deposit using an engineered hydraulic borehole mining technology.
This work indicated that a single borehole mining unit could produce approximately 500,000lbs of U3O8 per annum.
"The result of this preliminary evaluation indicates that Borehole Mining could be an alternative method of mining the Hansen Deposit" Mr Simpson, Managing Director of Black Range, stated.
Following receipt of these very encouraging initial results, Black Range will further evaluate the use of Borehole Mining in conjunction with Kinley, who are experts and pioneers in this method of mining.
