Abstract: Problems of modern mining include restriction of the scope of application of environmental and resource-saving technologies using the hardening mixtures in development of the ore field sites which are remote from stowing complexes, that significantly decreases performance indicators of metal ores underground mining. Experimental approach to the problem solution differs in the proof of technical capability and efficiency of the combined vibro - pneumo – gravity flowing delivery mode of the hardening mixtures to the distance exceeding possibilities of the existing delivery modes, in the study method of the vibration phenomenon of in the industrial pipeline of a special design. Results of industrial experiment confirm theoretical calculations about the possibility to supply the hardening mixtures of regular composition to the distance exceeding possibilities of the traditional pneumo-gravity flowing method due to reduction of resistance to movement of the hardening mixture in the pipeline as a result of friction. In the course of delivery by the pipeline, parameters of interaction of components of the hardening mixture improve with the increase in its durability, the completeness of subsoil use increases, the earth remains for agricultural production, and the load on the surrounding environment decreases.
