Rock quarries usually operate for at least 30 years and are developed in distinct benches or steps. A controlled explosion is normally used to release the rock from the working face. It is then transported by truck or conveyor to a crusher, where it goes through a series of crushing and screening …
Obviously, drilling and blasting are not used in the quarry, and the extraction process (in a bench of 8 m) is carried out using conventional earth moving equipment (hydraulic excavator with 3.3 tons capacity bucket) that loads the sand and gravel into trucks of 33 tons for transferring to the processing plant (Fig. 5.46).
The fill factor for loose material varies between 85 to 100 percent. Poorly blasted rock has a fill factor between 60-75 percent; average blasted rock, between 75-90 percent; and well-blasted rock, 80-95 percent. The bucket size needed is determined by dividing loose cu. yd. required per cycle by the bucket fill factor.
