3.1. Calculations of the productivity backhoe excavator In surface mining operations were the daily productivity of the ore to be hauled to the plant has been determined, it is also important to first estimate the productivity of the loader before estimat-ing the productivity of the dump trucks when trying to optimise the fleet due to the following
Production over a given time period of interest typically one shift can be calculated by the number of loads that trucks take to the dump 12 where N is the number of trucks in the system. Also production may be calculated from 13 shovel is shovel utilization and shovel is shovel loading rate. For shovel-truck type operations, the ...
OEE calculation for Shovel Shovels are used in open pit mining as primary loading equipment. Their performance and production controls the total output of operation. Therefore any production loss in shovel causes an increase in total production cost. Therefore the trend for those equipments require that the manager consider every possibility
trucks and shovels a part of the shovelas -truck systems. Dispatching is a dynamic process that requires continuous monitoring of routes and locations of trucks and shovels. Applying dispatching can either increase productivity of the shovel-truck system with the available equipment, or provide a desired performance with less equipment.
