Abstract: Underground mining of kimberlite fields in Western Yakutia is associated with the abundant flow of mine water in mine workings. Without the use of a sufficient number of pumping equipment, mine waters that penetrate into the underground mine workings make the process of extracting diamond-containing ore more difficult and, above all, unsafe for workers. Currently, in order to combat the mine water inflows in underground kimberlite mines, various single-flow centrifugal pumps are used, which have certain advantages and disadvantages when compared to each other. Since mine drainage is an integral technological process in the extraction of diamond-containing raw materials, increasing the performance of the related equipment is an important scientific and practical task. The main aim of the study: comparative performance analysis of various types of centrifugal pumps used in the process of underground mining of kimberlite ore in Western Yakutia. The methods used in the study: To achieve this goal we have used a comprehensive approach including: analysis of significant statistical and practical material on the performance of the above pumps as well as previously published works on the subject of research, experimental studies conducted in a laboratory setting on the basis of the cantilever pump K8/18, analytical calculations and computer modeling in the software environment “APM Win Machine”.

Key words: Mine mining water centrifugal pumps performance wear bearing
