1.Tsel master's thesis
The purpose of master's work is the synthesis of optimal performance by the algorithms and systems for monitoring and of mine ventilation process excavation sites with limited methane concentration in the transient and stationary modes at a safe level to ensure better security in the mine ventilation networks.
2. Relevance of the topic
Ventilation systems of large modern mines are fairly complex set of mountain ranges and facilities to ensure a safe and productive work of miners. It is impossible to realize of the main technological process of coal mining. Without effective were of vent system it can be attributed to the most important technological process of coal mines, its goal is to provide a comfortable working conditions of miners and the elimination of dangerous concentrations of methane in the mine atmosphere.
3.The planned scientific novelty of the results
1. To develop mathematical models of aerodynamics for mining ventilation network (MVN) working as objects of control, characterized by taking into account the real spectrum of aerodynamic disturbances.
2. Derive the equations of gas dynamic processes in mine workings and developed spaces, other with than a reflection of the characteristic properties of the excavation sites as objects of gas control through the use of the physical laws of motion of the methane-air mixture and the actual technical parameters of mining workings.
3. The structural-functional approach to the modeling of a controlled MVN with distributed parameters, using different compositions of the topological model developed by the dynamic components of the network.
4. Modify the method of optimal safe management of gas ventilation excavation sites by using sliding mode control mining impacts.
4. Planned practical results
1. The mathematical description and the development of mathematical models of aerodynamic processes transient in mine ventilation networks, the complexity of optimal and adequate dynamic properties of real workings in the mine for a substantial network of the frequency spectrum of aerodynamic disturbances and control actions.
2. The mathematical description of the development of reliable and dynamic models of excavation sites as gas control objects, taking into account the real spectrum of perturbations aerogazodinamicheskih and filtration properties of the excavation and mining sites worked-out areas.
3. Synthesis of quasi-optimal algorithms by dispatching automated control aerogazodinamicheskimi processes in a network with limited concentrations of methane at an acceptable level in the stable state and transient modes of ventilation.
4. Issledovanie quantitative and qualitative characteristics of the developed algorithms and software tools to support supervisory control circuit winding mining sites.
The object of study
The object of research is air-gas-dynamic processes in mine ventilation networks in the gas control system
Subject of research
The subject of this study is the optimal fuzzy control system of mine site ventilation with limited concentration of methane at a safe level when developing the given values of air flow rates.
Research methods
In the development of aerodynamic models of mining will be used common telegraph equation of dynamic air control processes as objects with distributed parameters, which are constructed on the basis of adequate approximate model given the limited range of actual production of disturbances in the air in the mine network.
