Hydrogeological parameters and prospective water inflows into designed open pit were calculated according to materials of experimental-filtration researches. Navay phosphate ores deposit (Venezuela) is a research object. From the beginning of 2006, specialists of «Belgorkhimprom» JSC have been participating in geological-prospecting works at the deposit. Experimental-filtration works were carried out in central hydrogeological well. Observations of the level in the process of pumping and level recovery were carried out in two observation hydrogeological wells, situated directly close to the central well (in 5 and 9.9 m respectively). Results, obtained during the hydrogeological researches, will be used both by «Belgorkhimprom» JSC (during the development of complex of measures, connected with open pit drainage, within Navay object measuring project), and by Pequiven Company (Venezuela) (for creation of safe conditions during the exploitation operations on extraction of phosphate raw materials).
