Abstract: The article presents a methodology of calculating the performance of hydraulic monitoring and suction-dredging complexes in stripping operations, which makes it possible to optimize its parameters in certain mining conditions. A new classification of Quaternary rocks has been proposed, which makes it possible to determine parameters of the complexes. Uniaxial compressive strength that depends on the internal friction angle and rock cohesion, has been adopted as a dedicated criterion to assign certain rocks to a certain group,. A formula has been established for calculating the effective range of the jet depending on the water pressure at the nozzle of the hydraulic monitor and the tensile strength of the rocks being developed. A computational model is provided to determine parameters of the technological scheme for rocks development using the hydraulic monitoring and suction-dredging complexes. Based on this model the water pressure at the nozzle of the hydraulic monitor has been established at which the effective range the hydraulic monitor jet should not fall below 30 m. Failing this, the equipment downtime increases significantly during relocation of the hydraulic monitor, which dramatically reduces the performance of the complex. The paper presents a methodology to justify the rational parameters of the hydraulic monitoring and suction-dredging complex depending on the strength properties of the rocks being developed. This, by adjusting the water pressure at the nozzle of the hydraulic monitor and the equipment of the complex, makes it possible to establish the linking criterion, i.e. the effective range of the hydraulic monitor jet, as well as the performance of the complex and its rational or optimal (with account for the process costs) performance indicators of hydraulic mining in open-pit conditions.
