This article deals with concerns of construction of subsurface structures with the use of shotcrete as a support, the samples of mine construction with application of shotcrete have been shown, in particular projected mine with vertical well bore. The calculation method for construction of well bore with the use of shotcrete support has been stated, the major analytical relationships have been set out, a graph showing the growth of strength in a support has been generated for several sites according to the results of actual geotechnical survey. The research of properties of concrete with fast development of strength has been implemented for mine engineering and construction of transportation infrastructure. The results of experimental analysis of shotcrete with organo-mineral and chemical additives have been listed. Performance improvement of physical and mechanical properties of shotcrete has been proven when the complex active nano agent added into composition of the binder. Improved kinetics of development of strength related to accelerated admixture helps in proportioning concrete compositions for practically any firm and medium-firm grounds during construction of support of subsurface structures.
