Abstract: The study contains results of studies completed to determine the bench width for backhoe hydraulic excavators. Bench width is among the main parameters providing efficient operations in open pits and quarries now a days. Scientists have developed various methods to define this parameter, however, they are mostly based on the experience gained from operation of rope excavators with rack crowded shovel. At the same time, there is no clear system for defining these parameters provided that all required set of calculation elements is available. Hydraulic excavators require less space on the working bench compared to rope ones with a front shovel with the same standard size. Bench width along the mining front varies within an average range, however, it cannot be less than the design minimum one. The method shown in this study allows determining the balanced bench width at different levels of open pits.
