Hydro-mechanized complex for the purification of mine waters from large mechanical impurities

A loading and delivery machines of the mechano-energetic sector of the underground kimberlite mine Udachny of AK ALROSA are characterized by frequent failures in comparison with other production sectors where similar equipment is used. The less reliable operation of these technological machines of the mechanoenergetic sector is explained by the premature loss of operability of electrical equipment as a result of contaminated liquid entering its elements during cleaning and rolling back of condensed mud deposits. It has been established that the most intensive silting at the mine under consideration is characteristic of the drainage mine workings of the district water-drainage system, the operation time of which between cleanings is usually up to five days. This research paper provides a detailed overview of known technological solutions to reduce the intensity of silting of drainage mine workings in conditions of mine water-drainage. It has been established that in order to reduce the intensity of silting of the water reservoir of the district water-drainage system of the Udachny kimberlite mine, it is necessary to minimize the ingress of large mechanical impurities larger than 0.2 mm into them as much as possible. To solve this urgent scientific and practical problem, the authors of the article proposed and sufficiently justified a special hydro-mechanized complex for cleaning mine waters from large mechanical impurities.

Keywords: kimberlite mine, mine water, water-drainage installition, mud, silting of the water reservoir, immersional pump, hydrocyclone, shale shaker.
