The Growing Challenge of Water in Strip Mining

Strip mining, also known as open- pit mining, accounts for a signitant portion of thee term 's mineral and coal extraction. While is an efficient methode for accesing shallow deposits, it carries a facionaal environmental cost, specilarly recurding water consumption. A typical strip mining operation cain consume millions of gallons of water daily for dust supressupression, ore conwaing, equipment coloying, and rimon transport.
