Surface mining: Depositing the material laterally. At the same time, it produces even, stable surfaces and embankments, and permits the selective mining of individual rock layers. And that's not all: Surface mining is a lowdust, lownoise method that causes no damaging vibrations and therefore permits effective mining of useful minerals close to residential areas or roads.
Aggregate mining operations share certain characteristics, but each one is unique and needs a mining plan tailored to its site. The information needed for a mining plan generally includes the following: • Inventory of the aggregate source including the shape, extent, and depth of the aggregate deposit and its relationship to groundwater.
