Cherednykova O. Mathematic aero-gas dynamic models and algorithms safe control ventilation of mine excavation areas

Subject: aero-gas processes in the mine ventilation network under the management of the ventilation excavation sites on the gas factor. The aim of the work: development of mathematical models aero-gas processes and algorithms of speed-optimal ventilation control dispatching algorithms for coal mine excavation areas with a limit methane concentration in transient modes at a safe level in order to improve the level of safety in the mine ventilation networks. Methods. Approbation of dynamic models of the air flow is performed by the methods of frequency mathematical modeling in the real frequency range with the boundary conditions for which the frequency characteristics of the workings theoretically substantiated. Approbation of gas-dynamic models for excavation site is made with the use of experimental data mining observations. Ventilation control dispatching algorithms for coal mine excavation areas have been developed the methods of the phase plane to the criteria of performance and security on the gas factor. The scientific value of the work: 1. Mathematical model of aero-gas processes have received the further development in ventilation networks. 2. The obtained results are the basis for the scientific substantiation of ventilation control dispatching algorithms for coal mine excavation areas . 3. Developed models are considerable contribution to the theory and modeling methodology managed objects with distributed parameters. The practical significance: the model of controlled mining ventilation network using the structural-functional approach to display the topology of the managed network with the component with distributed parameters, is implemented, improved structure, algorithms for systems of dispatching management of mining sites, and system software support of computer-aided speed-optimal. The results are implemented in the educational process, and also are used in the system of KAGI settlement at the stage of debugging software survey of the sensors, and in the "Donetsk Expert-Technical Center" with the thermal calculations of a climate of deep mines.
