In the article, technologies of pulp preparation and their characteristics and features are described. The technological processes of pulp preparation were studied, and on the basis of results the most promising method was selected for use in domestic mining and processing plants. Dimensions of the pulp preparation unit, which are limited by the upper ridge of the dam, and determined by the required capacity of the slurry, are substantiated. In the calculations in this research work, volume of technogeneous placer is determined according to the adopted specification of mining equipment and is assumed constant, while volume of water flow supplied from the pond is determined with taking into account the flow-pressure characteristics of the water supply system, which can be adjusted during the transition from card to card or transition to new store tier. In addition, rates of specific water consumption for pulp formation were estimated, at which type of slurry and mode of its flow along the highway are changed. A critical diameter of the pipeline was specified for the given parameters of the mining complex and the adopted pulp preparation system. According to the results of the research, parameters of hydromechanization technologies for the development of technogeneous deposits formed in the enrichment waste storage facilities are substantiated.According to the results of the researches and the obtained dependences, it is possible to develop recommendations for substantiating parameters of the processes of restoring the accumulation ability of the spit by using hydromechanization facilities. The results obtained during the work are intended for use by design organizations and mining and metallurgical enterprises to provide sufficient production facilities and to extend life of waste storage facilities by restoring their accumulation capacity.

Keywords:
