摘    要:文章提出我国金属矿山“超设计服务年限”,即矿山的“实际服务年限”超过了按照“合理服务年限”原则所确定的“设计服务年限”的那一部分“服务年限”的新概念。我国主要金属矿产25个矿种10 618座矿山的统计资料表明;70.87%的大型矿山超设计服务,“超设计服务年限”平均可达10.75年;中型矿山的79.07%“超设计服务年限”平均可达10.74年;73.41%的小型矿山的“超设计服务年限”平均仅有2.25年。我国25种金属矿产8 107座矿山“超期服役”为国家作出的“直接贡献”总共是;每年多产矿石29.21亿吨,多创产值3060.75亿元,多缴税金306.82亿元,多提供就业岗位606.33万人。“超设计服务年限”的新概念表明,我国大中型矿山所在的矿区,不仅大多具有较好的成矿地质条件和较大的资源潜力,而且还有随着勘查程度和认识水平的提高而进一步扩大资源潜力的可能。

关 键 词:超设计服务年限  矿山  金属矿产  资源潜力  成矿地质条件

Abstract:We put forward the new concept of service exceeding life which refers to the difference of the real service life and that of the originally designed for metal ore deposits. Statistics is made on 1068 mines of 25 metals of which 70.87% of the large deposits exceed 10.75 years averagely than that of originally designed service life, 79.07% of the medium 10.74 years and 73.41% of the small 2.25 year. Daring the exceeding years the deposits contribute 2921000000 t ores valued at 306075000000 RMB, tax of 30682000000 RMB to the state and 6060000 working position to people. So many ore deposits exceed their service life indicating that the large and medium ore deposit-locating areas are of preferable ore-forming condition and ore potential. And their ore potentiality would enlarge with upgrading of the prospecting data and ore-forming theroy.
Keywords:the exceeded service years  new concept  metal ore potential  enlightment
