Vygovs'ka D. A Substantiation of preparation parameters of stocks slopes steps of deep horizons (on an example of mines Donetsk-Makeyevka coal area).

Mines of Donetsk - Makeyevka coal area. Scientific and technical generalization both substantiation of preparation parameters and improvement of reserves stocks slopes steps of deep horizons for maintenance of high technical and economic parameters of operation of mines. The engineering -logic and economic analysis, statistical processing of the information with using of probabilistic methods, mathematical multifactor model, economic-mathematical models and their computer realization. The quantitative parameter dependences of reliability refining and developments from influence of the basic mining-and-geological and mine technical factors are established. The numerical values of rational parameters of panels division stocks slopes field on section (length of section along the strike, loading on section, amount of stages) are reasonable in view of reliability and influence of major factors. The methodical rules by definition of reliability parameters of basic processes are developed; The technique of de finition of optimum parameters of panel section for concrete conditions is developed. The developed technique at a choice planning solutions on improvement of flat coal seams on deep horizons is accepted CPU "Donugol". A coal industry, research and design institutes, Donbass mines.
