To develop new control algorithms for controlling slurry pumps, it is necessary to have a reliable mathematical model of their operation, convenient for computer simulation implementation. Therefore, the paper discloses a mathematical model of the joint operation of a centrifugal pump with a controlled asynchronous motor drive and a slurry pipeline. The results of transient modes computer simulation, carried out via the xcos application of the scilab software, are presented. This software is a freeware one and, therefore, available free of charge to most researchers. The paper provides an example of verification of the adequacy and performance of the proposed computer model, with the use of characteristics of the centrifugal slurry pump GrAT-225-67-3-2-2. The said model of a centrifugal pump is efficient and can be used during the study of dynamic processes in pipeline transportation systems, as well as in the synthesis of control algorithms for electric drives of pumping units.

One of the important parameters of using the hydraulic transport system in mining enterprises is considered. A method for regulating the ground pump drive and a computer model of the drive power stabilization system are proposed. The simulation was performed in the Scilab program. The performance of the proposed model was checked. The results of simulation with different values of the current and torque are shown. The efficiency of the proposed method for regulating the ground pump drive is evaluated.
