Mining Techniques for Sand Gravel ... Other Sand Mining Methods. 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.

Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world''s use of aggregates for concrete can be estimated at billion to billion tonnes a year for 2012 alone.
