How deep is a gravel pit?
QUARRIES MAY BE SEVERAL HUNDRED FEET DEEP.
How does gravel mining work?
Sand and gravel typically are mined in a moist or wet condition by open pit excavation or by dredging. Open pit excavation is carried out with power shovels, draglines, front end loaders, and bucket wheel excavators. In rare situations, light charge blasting is done to loosen the deposit.
