In this paper, performance assessment studies for hydraulic and cable shovels carried out on a nationwide scale in the surface lignite mines of Turkish Coal Enterprises are explained. The work was involved manual stopwatch surveys of shovel dig cycle times, estimation of bucket filling and hourly excavation capacity of shovels. The accumulated data is compared with the literature values in order to be evaluated in terms of ease of digging. The observed bucket size ranges of hydraulic and cable shovels varied from 2.5 to 10.5 and 4.5 to 25 yd3 respectively. The work efficiencies were established by considering observed and net outputs. Furthermore, the performance results were cooperated with geotechnical data to define the ease of digging
