人有生老病死,企业有兴衰存亡。矿山作为基础性的原料工业企业,自然也有一定的寿命。与其他企业不同的是,矿山的寿命一般较短(我国有色金属矿山平均为25年左右),并主要取决于矿床储量。即: 矿山经济寿命=矿床工业储量(万吨)/生产规模(万吨/年) 但实际情况比上式要复杂些。除了矿床储量可能会发生增减变化外,生产规模的实际形成还会受到能源供应、市场容量、产品价格、科技进步程度、某一时期内国家制订
People are sick and die, business is up and down. Mine as a basic raw material industrial enterprises, of course, have a certain life expectancy. Different from other enterprises, the life expectancy of mines is generally short (China’s non-ferrous metal mines average about 25 years), and mainly depends on the deposit reserves. Namely: Economic life of mine = ore industrial reserves (tons) / production scale (million tons / year) But the actual situation is more complex than the above. In addition to changes in the reserves may occur changes, the actual formation of the scale of production will be subject to energy supply, market capacity, product prices, the degree of scientific and technological progress, a period of time to develop
