绿色矿山是我国矿业实现绿色发展的战略依托,具有现实的可操作性,在实践过程中不断积累深化,其内涵在扩展,体现出包容性和开放性的特点。党的"十八大"将生态文明建设列入"五位一体"建设目标,在此背景下绿色矿山其建设模式内涵将有大的扩展与提升。绿色矿山概念内涵经历了两个发展,早期受主管行业推动,处于行业覆盖下,行业封闭式的矿山范围内的生态修复、绿化复垦等;后是由行业倡议、矿业响应,带有浓重行政色彩的治理行为。党的"十八大"召开之后,生态文明建设纳入我党执政的纲领性理念。党的"十八大"将生态文明建设列入"五位一体"的建设目标,在此背景下绿色矿山的建设模式及内涵将有极大的扩展与提升。 相似文献

党的十八大把生态文明建设列入"五位一体"建设目标,兼顾经济、资源与环境的协调发展,建设绿色矿山成为当前矿山建设的风向标和发展的必由之路。列举了国外在矿产资源绿色勘查开发中所制定的政策、采取的相关措施,旨在阐述我国在借鉴国外经验的同时,结合我国发展实际来建设绿色矿山的历程。通过对我国绿色矿山发展历程的分析,指出在新形势下,矿山生产企业应以矿产资源合理利用、节能减排、保护自然生态环境、矿地和谐为发展目标。政府相关部门要从实际出发,制定明确的奖惩机制,让企业把绿色矿山建设的理念贯穿整个矿山生产及生命周期中,最终达成资源、生态、经济、文明和社会效益相统一,实现人类社会的可持续发展。 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
