Identification of diagnostics states for dewater pumps working in abyssal mining pump stations

The problem of dewater pump model working in coal-mines identification is described in this paper. Our main purpose is to find parameters that describe diagnostic state of a pump at any moment of its exploitation. Basing on this we try to find how long the pump could work and what is the time to the next repairing. The mathematical method based on description of monitored parameters by means of mathematical equations and the knowledge based method consisting in identification of diagnostic states by means of clusterization are considered during data analysis. In the knowledge based method determining of approximate time to the next repairing is considered as a classification task.
