07.05.2021The mining fleet is one of the industry's primary sources of on-site greenhouse gas (GHG) emissions. Mobile mining equipment at a surface mine can account for up to 30 percent of on-site GHG emissions—or up to 80 percent if the mine doesn't have contiguous smelting or refinery facilities. Large mining haul trucks can represent more than

23.09.2005Impacts of surface mining on ecosystems were investigated in the Guangdong Dabaoshan Mine region, southern China. Significant soil acidification has been induced by mining activities which cause oxidation of metal sulfides contained in the mine spoils. Natural colonization of vegetation in the mine site has been impeded and this has resulted in severe
