试论我国矿业企业的技术创新

21世纪是知识经济时代，而知识经济是经济知识化和知识经济化这两种趋势相结合的经济形态。知识经济的时代是以创新为重要特征的，创新是知识经济的核心，也是提高矿业企业竞争力、促进矿业企业经济发展的动力。我国矿业企业技术能力不强，技术成果转化率低下，各种制度因素、经济因素制约着企业的技术创新。笔者从我国矿业企业的现状入手，力图分析矿业企业技术创新能力不强的原因，提出加快技术创新的对策。     

循环经济与我国矿业的可持续发展

发展知识经济和循环经济是21世纪人类社会发展的两大趋势，循环经济要求以环境友好的方式利用自然资源和环境容量，实现经济活动的生态化转向，其技术载体是可持续发展技术，或称环境无害化技术和环境友好技术，可有效地缓解当前人类面临的人口膨胀、资源衰竭和环境退化三大危机。传统的矿业开发是以大规模的生态破坏、严重的环境污染等为特征的，与可持续发展、环境无害化和环境友好相距甚远。我国的矿业开发主要指矿石采掘、选矿及冶炼三部分，如何使我国的矿业开发符合21世纪人类社会发展趋势——循环经济的要求，本文论述了循环经济与我国矿业的可持续发展的关系。

矿用防爆轴流对旋主要通风机叶片ANSYS模态分析及应用

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。
