Abstract: In the short time, almost all diamond mining in the Russian Federation will switch to underground mining. The underground mining of diamond-containing (kimberlite) ore involves the ingress of a liberal amount of water into the mine workings. Untimely pumping of water can lead to an emergency. Pumping of all the water coming into the mine workings of the kimberlite mines of the Russian Federation is carried out by the main pumping units, the reliability thereof is quite low. Mean time between failures of pumping equipment is about 350 motor-hours. Due to frequent failures of pumping equipment, the main drainage units of kimberlite mines are forced to operate in emergency conditions, which is categorically unacceptable. Based on the above, we note that improving the efficiency of operation of the main drainage units of a kimberlite mines is a very urgent scientific and practical task at the present time. This article presents a set of measures to ensure trouble-free operation of the main drainage units of kimberlite mines. This set of measures was developed by the author of the article based on the results of: surveys of engineering and working personnel of kimberlite mines of the Russian Federation, surveys of drainage units of kimberlite mines of the Russian Federation, as well as experimental tests and processing of significant practical material for the operation of the pumping equipment, and presented in the form of 8 positions. These practical recommendations can also be useful for other sectors of the national economy of the Russian Federation, where sectional pumps are used, in particular, in the coal industry.
