Problems of operation of electric pumping sectional type units on kimberlite mines of ALROSA and the ways of their solution

Abstract

The relevance. Russian Federation is one of the world's leaders in diamond industry. Today, the predominant part (about 95 %) of all Russian diamonds is mined on ore (kimberlite) and alluvial deposits, which are located on the territory of Yakutia. Practice shows that underground mining of kimberlite fields in Western Yakutia is associated with the abundant water flow to mine workings. Without application of sufficient number of pumping equipment, water penetrating to mine workings makes diamond extraction more difficult and un+ safe for people. Today, for dealing with mine water inflows the electric pump sectional type unit are used on kimberlite mines. As mine drainage is an essential process in diamond extraction, improving the reliability of the related equipment is the relavant scientific and practical task. Objects: electric pumping sectional type units of kimberlite mines «Mir», «Udachny», «Internatsionalny» and «Aykhal». The main aim of the research is to study the influence of different production factors, mainly hydrogeological conditions, on durability of pumping equipment of kimberlite mines drainage systems of «ALROSA» JSC. Methods. To achieve this aim the author has used a comprehensive approach including: analysis of the physico-chemical composition of mine waters, analysis of significant practical material by these pumping equipment work and previously published articles on the subject of research, experimental researches of kimberlite mines electric pump units of «ALROSA» JSC. Results. According to the results of the researches, the author proposed the recommendations for improving reliability of a pumping equipment of kimberlite mines drainage units, which are administered by «ALROSA» JSC.
