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.
Aggregate is mined from the earth, either dug out of pits or blasted out of quarries. This process has many significant environmental impacts. Creating the pits or quarries requires the removal of virtually all natural vegetation, top soil and subsoil to reach the aggregate underneath.
aggregate physical properties, and, in particular, gradation (size control). Establishing a stable production process may reduce variability of the product. EXTRACTION With the exception of slag and other manufactured aggregates most materials for aggregate production come from bedrock or unconsolidated deposits. The vast majority of materials ...
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.
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.

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.
Aggregates are important because of the qualities they possess such as strength, shape, size, texture, bulk, abrasion ability or resistance, medicinal, etc. For more than 50 years, General Kinematics has provided innovative vibratory equipment that is essential in the mining and aggregate manufacturing process.
