简介：2003年我区地质勘查工作上了一个新台阶，提交了可供开发的资源量，延长了矿山的服务年限．发现了一大批有进一步工作价值的矿产地和矿化线索，基础地质研究也取得许多新认识．今后地质勘查工作要继续坚持“主攻天山，深化阿尔泰山．开拓昆仑、阿尔金山”的总体部署思路，遵循“区划、区调、矿产普查、物化探和科研五统一”的工作原则，针对铜、金、富铁、富铅锌、富锑等国家和自治区急需的矿产及相应的重要矿床成因类型，以寻找大型-超大型矿床为突破口．兼顾可开发的中小型矿床．

简介：<正>尽管2001年的“9·11”事件对哈萨克斯坦经济造成了一定影响,但由于塔利班政权很快垮台,这种影响并没有像刚开战时那么大.2002年第一季度经济仍有较快增长.工业产值同比增长12.1％,农业产值增长5.5％,投资增长10.3％,货运量增长9％,零售商品总额增长10.4％.但外贸额却下降了4.9％.可是,到第二季度,工业产值、货物周转量、固定资产投资都比原计划数要低.第二季度,工业产值增长为5.9％,而上年同期增长为10.4％.其增长低于上年的原因是由于采矿业和加工业生产增速缓慢.工业产值第三季度增长9.5％,2002年前3个季度国内生产总值增长9.4％.2002年石油产量继续增加.10月该国能源与自然矿产部部长说,石油(包括凝析油)产量可达到4500×104t.
