Sand and gravel typically are mined in a moist or wet condition by open pit excavation or by dredging. Open pit excavation is carried out with power shovels, draglines, front end loaders, and bucket wheel excavators. In rare situations, light charge blasting is done to loosen the deposit. Mining
Sand mining is the extraction of sand, mainly through an open pit (or sand 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 surface.

practice in open pit mines. The application of sound geotechnical engineering practice is considered to be an integral component of Part 2 of the Mines Safety and Inspection Act 1994 (MSIA). It is emphasised that this guideline is not totally inclusive of all factors concerning the application of geotechnical engineering in open pit mining.

4/12/2020#0183;#32;Openpit mining uses large holes in the ground that are excavated to the depth of the desired product, and are common for sand, gravel and copper mines. Mining machines called draglines use a moving bucket to scrape away the soil lying over the ore deposit. Draglines can move the soil to a waste pile away from the pit, or dump the material into large trucks that transport it away from the site.
