FIELD: soil or rock drilling; mining.
SUBSTANCE: group of inventions relates to methods for predicting changes in an underground deposit and a method of predicting changes in submersible electrical pumping systems. Method of predicting changes in an underground deposit includes: creating a reference library of basic data representing submerged electric pumping systems in a state of suitability for operation for a plurality of conditions in the deposit; development of statistical model of deposit state, based at least in part on said basic data; development of statistical model of anomalies of submersible electrical pump system, based at least in part on said basic data; receiving operational data from the submersible electric pumping system deployed at the deposit; application of operational data to statistical model of deposit state and statistical model of anomalies of submersible electrical pump system; and generating output data which represent the probability that the state of the deposit has changed.
EFFECT: technical result consists in improvement of efficiency of technical assessment of submersible electric pump systems.
