矿井通风"人-机-环境"系统可靠性研究

On the Reliability of the MVS' "Human-Machine-Environment

矿井通风系统是矿井生产系统的重要辅助系统,其可靠性高低对矿井生产和安全管理有着直接的影响。在其生命周期中与其它子系统共同孕育发展,也是人机环境系统相互作用而构造的整体结果。对由人、机与环境组成的通风系统可靠性,除了研究机的可靠性之外,还应该对人和环境的可靠性进行全面而深入的探讨。用可靠性工程方法、从人机工程学的角度对矿井通风系统可靠性进行研究,给出了矿井通风"人-机-环境"系统可靠性的定义和数学模型。指出只有对系统进行全面分析,才能有效提高矿井通风系统的可靠性。

Mine ventilation system (MVS), a main auxiliary system of the mine production system, has a fatal affect on the safety of the mine. Its reliability is a result of other subsystems affecting each other in the spell of the lifecircle. Concerning to the reliability of the MVS that includes human, machine and environment, the reliability should be researched deeply, except that of 'Machine'. In this article, the reliability of mine is discussed by the method of RP. The definition and mathematic model of the MVS' 'humanmachineenvironment' are provided. The reliability of MVS will be promoted only by the thorough analysis to the whole system.
