This is silica mining. Fracking, a process used to extract natural gas and petroleum, depends on silica sand, or "frac sand" to produce the fossil fuels. A single fracking site can use millions of pounds of sand. The sand is blasted into wells to keep fissures in the rock open so that oil and gas can be released.
