Chernykh O. Substantiation of parameters and regime of complexness openly-underground exploitation of mineral deposits.

Dissertation is devoted to permission of problems of complex openly-underground development of ore deposits, to creation of scientific bases of the optimum mo-de and parameters of the openly-underground and underground works which create unique correlate technological complex at working off deposits on a complete depth and on all of area opened. In dissertation new principles of combination of the opened and underground works are developed with education between them correlate of technological complex and unique produced space, confirmed 11 inventions. Methodology of determination of parameters of openly-underground tier is developed; in thereby a graphic and analytic method of determination of his maximum depth and analytical methods of optimization of parameters is on the basis of experimental and industrial information. Methodology of determination of optimum scopes of the methods which create correlate technological complex at development of deposits on an economic rational depth and on all of areaon the basis of ecology and economic factors opened, underground and openly-underground is created.
