【摘要】 为不断改善矿井通风状况,进一步促进安全生产,1992～2004年山东招金(集团)公司同科研单位合作,采用专家系统决策优化设计,主辅风机机站通风方式,优选节能风机,利用采空区回风,规范化综合测评等技术,对11个矿井通风系统进行设计建设与技术改造的研究和工程实施。实践表明,建立的通风系统运行质量显著改善,风机运行效率平均达71.07%,有效风量率达68.54%,通风节电效益明显,其中金翅岭金矿等5个矿山实际年节电总计215.75×104kW·h。长期运行表明,系统稳定,通风状况明显改善,有力地促进了安全生产。更多还原

【Abstract】 To continuously improve the mine ventilation conditions and further promote the safety production, Shandong Zhaojin(Group)Co., in cooperation with scientific research institutions, carried out the investigation and engineering execution of the building and technical transformation of its eleven mine ventilation systems in 1992`~ 2004, in which expert decision system was used to optimize the design, the main and auxiliary two-stage fan station ventilation mode adopted, energy-saving fans were selected ,the turn wind from mined-area was utilized and standardized comprehensive testing technique applied.The practice showed that the operation quality of the ventilation systems was greatly improved, with the average operational efficiency reaching 71.07% and effective wind amount reaching 68.54%.The benefit of electricity saving in ventilation is very evident: five mines including Jinchiling Gold Mine have saved annually altogether 215×104 kW·h.The long term operation of the mine ventilation systems show that they are stable and have remarkably improved the ventilation conditions, thus greatly promoting the safety production.更多还原
