The current rates of industrial development require an increase in the consumption of mineral resources. At the present time acutely raised the question of ensuring the Russian metallurgical industry manganese raw materials, because, on the one hand, the main sources of manganese ore moved to the Ukraine, Georgia and Kazakhstan, and on the other of consumers manganese are the all steel industry and mechanical engineering. The speedy development of deposits of ferromanganese nodules (FMN) of marine and ocean deposits will significantly eliminate the dependence on imported manganese strategic raw materials. For effective development of offshore fields FMN, especially in deep water, need reliable means of mechanization hydraulic hoisting rock mass with sufficient capacity. Presently known devices for mining of solid minerals from offshore fields is not effective enough and do not meet modern requirements for security, performance, energy consumption and environmental friendliness. Insufficiently studied questions remain about the influence of hydrostatic pressure determined by the depth of the capsule on performance and power characteristics of the mining equipment and depending on the type of system performance dredge device and its parameters. This paper presents the results of studies of the effect of the laws of hydrostatic pressure, determines the depth of of immersion of the intermediate buffer on the energy consumption of the mining process with a substantiation parameters of soil intake devices with hydraulic drive.
