金属矿山井下通风系统人机工程可靠性分析

运用可靠性工程和人机工程理论，结合采矿技术工艺，研究了矿井通风系统的构成及其特点，分析了影响矿井通风系统可靠性的各类因素。影响矿井通风网络可靠性的主要因素是矿井通风方式，有害角联网络和通风网络结构的变化。影响扇风机正常运行的主要因素是扇风机的选型，设备固有的质量，设备的安装、使用和维护管理，设备的安置环境，设备的操作者以及主扇风机的工作方式。矿井通风控制设施的实现改变了网络分支巷道的风阻，会对系统可靠性产生重要的影响。井下主要的采矿工艺过程，如运输提升、溜井放矿、井下爆破等环节，将对矿井通风系统的风流运动产生严重的扰动作用。

Analysis on Ergonomics Engineering Reliability About Underground Ventilation System of Metal Mine

With the use of reliability-engineering and ergonomics theory, combined with mining-processing technology, the composition of the mine ventilation system and its characteristics, various factors which can impact the reliability of a mine ventilation system have been approached in detail.It indicates that the main factors which will impact the reliability of the mine ventilation network are the mine ventilation system, the harmful diagonal structure of the network and changes in ventilation network. The main factors which will impact the normal operation of the fan are the types of the fan, its inherent quality, installation, use and maintenance management, the placement environment of equipment, equipment operators, and the method of operation of the main fan. The effectiveness of mine ventilation control equipment changes the resistance in the network branch roadway, which will have a major impact on the system's reliability; the main underground mining process, such as haulage and hoisting, ore-pass draw, underground blasting and other activities, will cause a serious disturbance of air-flow to the mine ventilation system.
