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.
This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western U.S. mining operations. All costs listed are in 2012 US. The key design criteria
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 worlds use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.
Carr Brothers and Sons is a premier sand, stone, and gravel company located southcentral Michigan. Founded in 1957, Carr Brothers has been owned and operated by the same Michigan family for over
Openpit, opencast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wallpit mines are used when deposits of commercially useful ore or rocks are found near the surface.

The U.S. Environmental Protection Agency describes sand and gravel as granulated material that results 34from the natural disintegration of rock or stone.34 The deposits of these materials are generally near the surface of the Earth and in wet areas. The locations are suitable for open pit mining and dredging
By far the largest mining endeavor globally is digging up sand, mainly for the concrete that goes into buildings. But this littlenoticed and largely unregulated activity has serious costs damaging rivers, wreaking havoc on coastal ecosystems, and even wiping away entire islands.
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.
The White Silica Sand Company Pit is near Caryville, Tennessee. The White Silica Sand Company Pit is a surface mining operation. Initial production took place in 1929 and overall output was considered to be small size. The ore mined is composed of sandstone. The ore body is described as tabular shaped of unknown dimensions.

Sand mining is the extraction of sand, mainly through an open pit but sometimes mined from beaches and inland dunes or dredged from ocean and river is often used in manufacturing, for example as an abrasive or in is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road can replace eroded coastline.

scale mining by dredging artificial sand pits or by removing existing sand banks will have a significant impact on the nearfield and farfield morphology increased coastal erosion.
The physical and environmental impacts of sand mining occur due to excavation that is taking place in the study area. Similarly, Ikhsan et al. 2009 and Lawal 2011 in their studies

After processing, the sand is transported to storage bins or stockpiles by belt conveyors, bucket elevators, or screw conveyors. Industrial Sand And Gravel Industrial sand and gravel typically are mined from open pits of naturally occurring quartzrich sand and sandstone. Mining methods depend primarily on the degree of cementation of the
Sand mining is highly detrimental to the surrounding environment. Sand mining is the process of extracting sand from an open pit, sea beaches, rivers and ocean beds, river banks, deltas, or inland dunes. The extracted sand can be used for various types of manufacturing, such as concrete used in the construction of buildings and other structures.
