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 25.9 billion to 29.6 billion tonnes a year for 2012 alone.

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.
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.

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. A World of Minerals
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.
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.
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.
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 ...
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.
