Okalelov V. Scientific principles of functional-structural optimization of models for mine tunnel networks in coal mines

Dissertation is devoted to the problem of increasing design reliability and efficiency for mine tunnel networks by taking into account their technological-functional operating quality, regularities of development in time and space, as well as probability of keeping mine works in various-type uniformity and difficult conditions of coal layers bedding. The idea of this work is in functional-structural description of mine tunnel networks at different stages of their development taking into account favorable conditions of coal lay-ers bedding. This work has given the substantiation of new criteria of optimum design decisions, which considers probabilistic nature of output information. For calculation the indexes, which are included into economic-mathematical model of criteria, there was de-veloped the set of identification systems and models, which are grounded on the com-bined using of heterogeneous sequential statistical analysis and linear discriminant func-tions, that provides high prognostical reliability. To consider the influence of output data errors onto their results the regularities of their formation are found and the necessary methods are developed. The generalized functional model of mine tunnel networks is de-veloped as well as generative methods of the project and criteria for their estimation. Choice of material carriers of functions, which are introduced into functional model, is made by creating and analyzing functional-structural models of mine tunnel networks. Their estimation is performed using developed private criteria that is resulted in forma-tion of subset of prevail options. From it using the developed scalar criteria the optimum variant is chosen finally, for which there calculated the probable loss from refusal or ap-proval to invest this project's realization with optimum mine tunnel networks. For operating coal mines improvement of mine tunnel networks is made on the base of their structural-cost description. The main regulations of developed method for optimi-zation of mine tunnel networks are introduced in the form of standard document, separate projects and recommendations.
