Abstract:



Purpose.
To substantiate a rational schedule for the combined dragline-truck operation taking into consideration a coefficient of mining in the context of the pit.


Methodology.
Mathematical and graphical modeling was involved while determining a coefficient of mining concentration in the pit as well as feasibility analysis to select a rational procedure scheme for dragline operation.


Findings.
Recommendations for the selection of rational dragline operation, while truck loading in the context of Motronivsko-Annivskyi pit, have been developed taking into consideration mining concentration degree in the pit. It has been determined that bottom dragline unloading into a truck, located in the central part of bench mining width, as well as the dragline position at 0.5 A distance from the bench crest, is the most efficient plan of action for the conditions. Technological scheme to develop Motronivsko-Annivskyi pit has been proposed.


Originality.
Dependence of the mining concentration in the pit upon the parameters of development system elements according to different technological schemes has been derived. The dependence helps estimate development cost for overburden rocks using draglines with direct unloading into trucks.


Practical value.
Technological schemes for the combined dragline dump truck operation have been developed. Their use makes it possible to cut the prime cost of overburden activities. Implementation of the proposed solutions helps cut stripping cost by UAH 79.65 million a year if annual overburden volume is Qrozkryvu - Qstripping = 13.5 million m3/year.
