Abstract.

The paper describes a process of preparing and obtaining experimental data and physical modeling of periodically sheared (cavity) fluid flow in technological borehole on purpose to control and determine values of hydrodynamic parameters for a device of hydroimpulsive action.

Sequence of operations has been considered for adapting PowerGraph software and modeling of the impulse injection of fluid with the help of high-pressure hydraulic bench.

The simulation results will be used for giving background for rational range of operating parameters of the hydroimpulsive action device used for hydraulic loosening of outburst-prone coal beds.

Keywords:

software, simulation, impulse injection, coal bed.
