矿山服务年限(service time of mine),指一个矿山从投产开始到开采完毕的全部时间。当矿床的工业储量一定时,年产量过大或过小就会使矿山寿命过短或过长,都会影响到矿山企业的经济效益。因此,根据市场需求、矿床规模和企业的经济效益,正确处理矿山寿命与矿山年产量之间的关系,是矿山设计中的一个重要问题。
前言:利用构造控矿原理,采用坑钻相结合的方式,探明新增地质储量,延长矿山服务年限。
Using the principle of "ore deposit is controlled by structure" and through combining of trench with hole, the new geological reserves of ore are detected that prolongs the service life of mine.
南芬铁矿目前正在进行的三期境界开采的服务年限已经不长了,矿山需要马上着手进行下期深部开采设计。
It will be a short time for Nanfen open-pit iron mine to mine in the third stage. The mine should be engaged on deep part mining design at once.
