An Assessment of Environmental Impacts of Sand and Gravel

Sand and gravel mining refers to the actual process of removal of sand or gravel from a place of occurrence. The increase in demand for sand and gravel for construction purposes has placed immense pressure on the environment where these resources occur. Miners employ different methods of extraction along river channels and their flood plains.

River Sand Mining and Mining Methods SpringerLink

13/06/2014 Different mining methods (mechanical or manual) are adopted for the extraction of sand from these sources under dry (above water table) and/or wet (below water table) conditions.

sand and gravel by quarrying and by the extraction of sand and gravel from rivers and offshore sandbanks (coastal and marine extraction). Quarrying involves the removal of the desired rock from “beds” or seams relatively near the surface by means of an open pit. These pits often occupy a large area of land for excavation of the rock and disposal of waste rock. Quarrying and Dredging operations

Environmental Effects of Sand and Gravel Mining on Land

The increase in the demand for sand and gravel for construction and other purposes such as flood control has placed immense pressure on the environment where sand and gravel resources occur. This study was carried out to determine the environmental effects of sand and gravel mining in Luku, North central Nigeria, using field observations and laboratory analysis of soil samples.

Operations include the wet excavation of riverbeds for gravels and the dry pumped excavation of floodplains. The advantage in the later method is the ease of excavation, whereas the pumping comes at a cost as well.

Impacts of Sand Mining

Sand-and-gravel mining in stream channels can damage public and private property. Channel incision caused by gravel mining can undermine bridge piers and expose buried pipelines and other infrastructure. Several studies have documented the bed degradation caused by the two general forms of instream mining: (1) pit excavation and (2) bar skimming. Bed degradation, also known as channel
