Mining Techniques for Sand & Gravel | Sciencing
Sand dunes can also be mined by dredging or hydraulic methods. This involves a high pressure jet of water to wash the sand into a pond where it is pumped to a storage pile or tank. Where sand is present in the form of loose sandstone, drilling and blasting are necessary. The blasting reduces the sandstone to smaller pieces that are …

Do Deeper Wells Mean Better Water?
groundwater: The saturated sand and gravel is referred to as an aquifer. An aquifer holds water in the spaces between grains of sand or cracks in rocks, and pumps then draw the water out of the aquifer and into wells. • Shallow wells are more susceptible to contamination.
