Shabaev O. Scientific Foundation for Analysis and Synthesis of Mining Machines as Mechatronic Systems

The operation processes of the mechatronic excavating machines are the object of the investigation. The goal of the investigation is development of the theory and analysis of mining machines as the mechatronic systems which provides the raise of their technical level and efficiency of application based on intellectualization of the operation process control system. The investigation methods are as follows: experimental determination of the regularities of the operation process of the coal-face destruction in representative production and bench conditions; processing of the results of the natural and computing experiments has been made by the probability theory, mathematical statistics and random process theory methods ;to develop the mathematical models of the analysis of the operation processes of the mechatronic excavating machines the methods of theoretical mechanics, analytical geometry and rock cutting theory were applied; the adequacy of the developed models was proved by the methods of the parametrical identification with the further comparative analysis of the results of the natural and computing experiments. The scientific results are as follows: the development of the theory of the mechatronic mining machines operation based on the stated regularities of the influence of the principles of the intellectual control system building which provides the adaptive optimization of the coal-face destruction working process on the machine usage efficiency; the development of the mathematical model complex to do analysis and synthesis of the mechatronic mining machines. The practical results are as follows: software to simulate mechatronic mining machine operation processes; the algorithm of the adaptive optimization of the duestruction mode parameters; the functional and structural models of the mechatronic shaft-sinking set. The work novelty is as follows: it is the first time when the insufficient efficiency of the usage of the potential of the shaft-sinking set under its manual control has been stated - the productivity of the mining massif destruction makes up 40% of the possible one; the mechatronic excavating machine operation process is adequately described by the aggregate of the mechatronic module mathematical models being developed for the first time and the control intellectual system which forms the optimal algorithms providing for the rational application of the stable moment and the drive heat power during the coal-face machining; the influence of the actual resource of the shaft-sinking set on its monthly deepening rate the value of which is the exponential dependence on the deepening daily rate has been stated for the first time. The results of work are applied to make and modernize the shaft-sinking sets and high-speed excavating machines. The application area: mining machine building.
