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.

11/95 Sand And Gravel Processing Sand And Gravel Processing Process Description16 Deposits of sand and gravel, the unconsolidated granular materials resulting from the natural disintegration of rock or stone, are generally found in nearsurface alluvial deposits and in subterranean and subaqueous beds.

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Nov 17, 2006· Where mining activities result in the removal of large volumes of bed material, changes in wave transformation, storm surge, bottom currents, and the dynamics of the shoreline can occur (Hobbs, 2002). Of all seabed mining activities aggregate extraction is by far the largest and most widespread. Statistics are difficult to obtain from most ...

Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.

The choice of excavating equipment is based on whether the gravel is mined dry or wet. Pits of varying shape, size and depth are excavated during the process of extraction. During the mining process excess water may have to be pumped from the pits and when extraction is completed the pits may fill with water derived from the surrounding aquifer.

Sand and gravel extraction. 04. Morphological alterations General description. Sand and gravel are crucial resources for economic development activities, such as road building and concrete production. As a result, sand and gravel mining is a major economic activity that is often carried out within river channels and floodplains.

Instream mining involves the extraction of coarse sand suitable for concrete slabs whilst flood plain mining involves the extraction of fine sand suitable for brick laying and plastering. Results of the field investigation revealed that instream mining is the prevalent type of sand mining .
