At final stages of coal extraction in some open pit mines in Kuzbass, it is required to repile earlier hydraulic fills situated above commercial reserves. Based on the analysis of changes in physical and mechanical properties of hydraulically filled rocks, the authors propose an integrated re-fill technology as well as substantiate a new method of hydraulic fill replacement and treatment. In the proposed hydraulic re-fill method, safety and efficiency of mining is ensured both by the set of hydro-mechanized technologies with application of appropriate equipment to fit physical and mechanical properties of rocks in the hydraulic fill zones under treatment, and also by the sequence and combination of these technologies. The relations are found for determining parameters of hydraulic equipment set composed of jet gun and suction dredge for development of earlier hydraulic fill. These parameters should ensure stable operation of the hydraulic equipment set and take into account properties of rocks and organizational and technological factors. According to the estimate of influence exerted by geotechnical conditions on the hydraulic equipment set efficiency, the increase in the pressure head at the jet gun nozzle from 1.2 to 2.0 MPa raises the hydraulic system capacity by 51–84 m3/h. The intensity of the improvement lowers with increasing pressure as with upgrading category (group) of rocks treated by the jet gun. For simplifying calculations in selection of optimal parameters for the hydraulic equipment set, the empirical dependence of its capacity on specific water flow rate during joint development of hydraulic fill by the jet gun and suction dredge is proposed.
