Why We Need Full Cost Accounting for Aggregate Mining

In many areas, aggregate is derived primarily from alluvial deposits, either from pits in river floodplains and terraces, or by in channel (instream) mining, removing sand and gravel directly from river beds with heavy equipment. The primary type of mining done in the Houston area is floodplain mining.

Geomorphic and environmental effects of instream gravel mining

Instream gravel mining involves the mechanical removal of gravel and sand directly from the active channel of rivers and streams. Active channel deposits are desirable as construction aggregate because they are typically durable (weak materials having been eliminated in river transport), well sorted, and frequently located near markets or on transportation routes.

Sand and Gravel Mining Industry Additional Information

Sand and Gravel Mining Process Once an aggregate deposit is found, the first step in extracting the sand and gravel is to clear the surface of vegetation and topsoil and dig a pit. Since the water table is so close to the surface in Nebraska, the pit fills with water and forms a lake.
