Abstract: Blasthole stemming has a major impact on blasting operations. Depending on the stemming material, different types of equipment are used, one of which is described in this article. The article presents the ZM-7-G stemming truck manufactured by AZOTTEKH LLC, which is designed for mechanized stemming with loose material. The stemming truck complements a range of machines for mechanization blasting operations and improves the blasting efficiency, reducing the flyrock zone and enhancing the environmental situation in the quarry areas. An optimal hydraulic circuit is selected based on this model and taking into account the hydraulic fluid flow rate and pressure of the safety valves set to a specific value. Implementation of the hydraulic circuit with separated hydraulic fluid flows ensures efficient maintenance and economical consumption of the hydraulic fluid, correct operation of the crane with the rated capacity, as well as safe operation of all actuating mechanisms. Conclusions are made on operation of the telescopic crane with a clamp bucket, and a description of the selected hydraulic system is provided.
