and size of hauling unit (trucks) to loading unit (wheel loaders and hydraulic shovels) need to properly match in order to provide the best possible fleet match [7]. The combined task of loading and haulage are the fundamental in the mining industry. In the simplest scenario, a loading device is used to load fragmented rocks (run-off mine) Find the soil’s load factor and shrinkage factor. 1 ٢٣. Soil Volume-Change Characteristics XIV. Solution Load factor = weight in loose unit volume weight in bank unit volume. Load factor = 1483 /1839 = 0.806. Shrinkage factor = weight in bank volume weight in compacted volume.

Therefore, the production of equipments used in each step depends on the production of previous equipment. That means utilization of each equipment affects the others. • The capacity of mining EARTHMOVING MATERIALS AND OPERATIONS Introduction to Earthmoving Earthmoving is the process of moving soil or rock from one location to another and processing it so that it meets construction requirements such as location, elevation, density, moisture content etc. Activities of earthmoving: Excavation, loading, hauling, damping, spreading, compacting, EARTHMOVING MATERIALS AND OPERATIONS studylib.net
