Аннотация

Subjects of research: orc deposit, exploited methods of UL on the conditions of using horizon mining system. Purpose of work: developing computer model of UL in heterogeneous environments in the realization of horizon mining systems for the analysis and decision making support in the control of technological processes of UL. Methods of research: methods of control theory, mathematical modeling, finite-difference methods and computational experiment. The results obtained and their novelty: mathematical model of controlling UL processes was developed on the conditions of horizon mining systems; dynamics of pressure change and the values of reagent concentration in the various values of outcome parameters, influencing on the behavior of technological process of UL on the conditions of horizon mining systems, was studied; computer model for carrying out computational experiments and visualizing the results in two dimensional and three dimensional graphics was developed; software package of UL process in the conditions of horizon mining systems for supporting making technological decisions in the control of mine workings was developed. Practical value: developed computational algorithms and computer model can be applied for the analysis, prognosis of the parameters of leaching process and decision making for controlling its parameters on the purpose of optimal extraction of minerals from real deposit mines on the conditions of horizon mining systems of mine workings. Degree of embed and economical effectivity: obtained results were applied in the mine North Bukinai NMSK, the act of applications was taken. Developed software was registered by Government Patent Committee of Uzbekistan. Field of application: mineral deposit mines exploited by the method of UL.
