本文基于“全国地质勘查成果直报系统”数据,汇总统计了2014年全国铁矿资源勘查的投入、工作量和进展情况,总结了2014年我国铁矿勘查形势的主要特点,初步展望了2015年形势。2014年我国矿产勘查整体形势继续下行调整,其中,铁矿勘查投入资金共计25.54亿元,同比减少27.9%,投入钻探工作量164万米,同比减少28.5%。研究认为,2014年铁矿石价格震荡下行、矿业市场不景气影响了企业投资铁矿勘查热情,受改革新政影响财政资金正逐步减少勘查投入,铁矿石资源新增态势持续走弱,主要产铁基地铁矿石产销快于新增速度。预计2015年铁矿资源勘查形势仍将继续下行调整,乐观估计铁矿勘查投入有望在2016年探底。 相似文献

本文分析了1981~2015年我国非能源矿产勘查投入、成效变化与影响因素,以期为矿产勘查形势预测奠定基础。非能源矿产勘查经历了平稳发展、持续低迷、快速发展和调整下行四个阶段,根据矿产品供求、矿业利润与勘查投入关系推测,未来几年矿产勘查或将延续深度调整的趋势。在快速工业化时期,有色金属和黑色金属矿产重要程度日益上升,而到工业化后期贵金属和三稀金属重要程度开始上升。相同矿产勘查投入所获得的新发现矿产地与新增查明资源储量总体呈减少趋势。市场经济条件下,经济发展、矿产市场与矿产开发对矿产勘查活动有着直接的影响,在变化趋势上矿产勘查投入可能比矿业成本费用利润率延迟1~2年。 相似文献

中国铁矿资源的现状与对策 总被引:2,自引:0,他引:2
中国铁矿资源具有分布广泛、但又相对集中,矿床类型齐全,贫矿多富矿少、矿石类型复杂,伴(共)生有益组分多、综合利用难度大等特点.近几年,我国铁矿资源储量整体呈下降趋势.2008年,我国铁矿石产量为8.12亿t,进口4.44亿t,对外依存度为52.24%.而从战略的角度看,铁矿石的供应不能主要依靠进口.为此,必须制定相应的对策和采取相应的措施,如加强地质勘查投入,在矿山深部和外围寻找接替资源;注重应用找矿新技术和新方法;加强中国西部及边远地区铁矿资源的勘查工作等,从而保证铁矿资源的安全供给;实施"走出去"策略,并购国外矿业. 相似文献

高效节能矿用防爆对旋主要通风机的叶片是主要通风机运行的关键部件,叶片在运行时不断受到气流的作用力,从而使叶片产生振动,当叶片振动的频率与叶片的固有频率接近时,容易产生共振从而导致叶片的断裂。一旦叶片断裂时,对主要通风机的安全运行产生致命的影响,从而导致矿山、化工等企业发生重大事故,将会产生不可估量的损失。基于有限元分析软件ANSYS,对高效节能矿用防爆轴流对旋主要通风机叶片进行模态分析及产生对应的六阶模态频率,对主要通风机叶片的运行频率、固有频率及产生的共振问题进行了原理分析,并且解决了叶片频率共振的问题,从而为主要通风机叶片结构设计提供理论依据,并对主要通风机叶片的安全运行提供保障。 相似文献
