吉尔吉斯斯坦位于中亚的核心地域,陆路边境分别与中国、哈萨克斯坦、塔吉克斯坦、乌兹别克斯坦接壤,边界线总长4170km,国土面积19.99×104km2,全国总人口600余万人。吉尔吉斯斯坦拥有优越的地理条件和丰富的矿产资源,逐渐被世界各国和国际矿业企业看好,成为外资争夺的重点区域之一。中国经济长期稳定增长,需要安全的矿产资源保障。在"一路一带"背景下,我国地勘单位及矿业企业"走出去"是保障国内矿产资源需求的重要举措。在我国地勘单位及矿业企业"走出去"过程中会面临各种各样的问题与风险挑战,如何高效矿业投资选区及风险防范显得尤为重要。通过对吉尔吉斯斯坦地质工作程度、矿产资源概况、矿业勘查开发现状、投资环境及资源潜力分析方面分析研究,进而提出我国地勘单位及矿业企业对吉尔吉斯斯坦矿业投资选区方向及风险防范建议。 相似文献

蒙古国矿产资源丰富,是中国企业走出去参与国际矿业开发投资的重要国家之一。但是,由于蒙古国外交平衡战略、投资和法律法规等政策多变、矿业市场竞争激烈、开发投资成本提高等因素制约,中蒙矿产资源开发合作时常受阻。随着蒙古国矿业投资相关法律法规的不断完善,特别是中蒙关系提升为全面战略伙伴关系,中蒙合作开发矿产资源进入历史最好的合作发展时期。中国企业应抓住机遇,坚持互利共赢原则,重视环保,惠及民生,承担社会责任,积极参与蒙古国矿业投资开发。 相似文献

几内亚以其丰富的铝土矿和铁矿资源逐渐成为非洲矿业投资领域的热点地区之一。研判几内亚矿业开发形势及前景,对于加强我国与几内亚矿业合作以及拓展"一带一路"倡议意义重大。本文阐述了几内亚矿产资源条件、矿业开发形势以及中资企业在几内亚矿业投资现状,进而对在几内亚矿业开发的主要风险进行了分析,并对几内亚矿业开发投资提出了一些建议。认为中几两国在矿业开发领域具有良好的合作前景,建议矿业企业在前期有必要开展几内亚基础地质调查工作,在此基础上以铝土矿和铁矿资源为勘查开发重点,并进行配套的冶炼加工产业投资,以实现双方互利共赢,共同发展的目标。 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
