【摘要】 综采工作面是煤矿生产系统的重要组成部分,其系统可靠性直接影响着煤矿的生产。本研究根据系统工程、可靠性理论、人机工程和系统动力学等相关知识,将煤矿综采工作面视为一个由人、机和环境组成的逻辑系统,并从这三个组成要素出发,对综采工作面人-机-环境系统可靠性进行了分析:在分析工人人因失误的失误模式的基础上,对人因失误的失误原因和失误机理进行全面的研究,建立煤矿人因失误的量化模型,并进一步给出煤矿人因可靠性的计算方法。在分析设备故障模式的基础上,对设备故障原因进行深入的探讨,同时建立设备可靠性计算公式,并进一步给出设备的维修密度函数、最经济计划维修周期和设备大、中维修周期的计算方法。在分析环境因素的影响基础上,全面阐述综采工作面可控制环境因素(微气候、噪声、照明和空气环境)对工人的影响,并给出相关计算方法。最后应用系统动力学原理,建立综采工作面人-机-环境系统可靠性模型,通过对模型进行实际模拟和敏感度分析,找出提高综采工作面人-机-环境系统可靠性的途径,为提高综采工作面人-机-环境系统可靠性提供理论依据。更多还原

【Abstract】 The fully-mechanized face is an indispensable part of the colliery productive system and its system reliability has a direct influence on the production of collieries. According to the relevant knowledge of system engineering, reliability theory, man-machine engineering and system dynamics, this thesis regards the fully-mechanized face of coal mines as a logical system composed of man, machine and environment and analyzes the reliability of man-machine-environment system of the fully-mechanized face in terms of the three components as follows:Based on the analysis of the worker’s human mistakes modes, a comprehensive research on the causes and mechanism is carried out and the quantifying model of colliery human mistakes is formed. Furthermore, the computing methods for the colliery human reliability are given;Based on the analysis of the equipment failure modes, a profound inquiry into the causes of equipment failure is conducted and a computing formula is proposed. Moreover, the consistency function of equipment maintenance, optimal planned maintenance period and the computing methods of large or medium-scale maintenance period are provided;Based on the analysis of the environmental influences, the effects of the controllable environmental factors (microclimate, noises, illumination and air condition) on the worker and related computing methods are fully illustrated.Finally, a model of the man-machine-environment system reliability of the fully-mechanized face is established by applying the system dynamics principles. Through the practical simulation and susceptibility analysis of the model, the approaches for improving the man-machine-environment system reliability of the fully-mechanized face are suggested as corresponding theoretical basis.更多还原
