【摘要】：煤矿综采放顶煤工作面是一个复杂多变的人—机—环境系统。由于人自身生理、心理与行为特性中的缺点，机器设备本身的设计缺陷与运行中的隐患，以及作业环境的恶劣程度与地质条件的不确定性，这些因素都是造成事故，影响生产效率的主要因素。通过优化人、机器、环境三个系统要素，，从系统匹配、协调的角度出发，研究使综放工作面人—机—环境系统运行状态达到安全目标最优，是实现煤矿安全高效开采的一个重要途径。在人—机—环境系统工程、安全心理学、人机工效学理论研究的基础上，分析了煤矿综放工作面人员、机器、环境三大系统的构成要素，最终选取了影响工作面安全高效开采的9个人员相关指标、6个机器相关指标和7个环境相关指标。从协同学理论、耦合理论和熵理论的角度分析了综放工作面系统性特点，并说明了综放工作面系统相融性是指工作面人、机器、环境三个系统之间相互配合、相互协调、相互促进的动态关系，其目的是通过系统相融实现工作面安全高效开采。根据物理学中的容量耦合度模型与系统协调度的概念，引入了人—机—环境系统相融度模型，根据此模型对山西某矿61B3工作面进行了相融度评价分析，并根据评价结果从人员、机器设备、环境三个方面提出了技术与管理措施。最后验证了相融性的提高利于工作面生产的安全高效性。
[Abstract]:The fully mechanized top coal caving face in coal mine is a complex and changeable man-machine-environment system. Because of the shortcomings of human physiological, psychological and behavioral characteristics, the design defects and hidden dangers in operation of the machine itself, as well as the bad degree of the working environment and the uncertainty of geological conditions, these factors all cause accidents and affect production. By optimizing the three system elements of man, machine and environment and starting from the angle of system matching and coordination, it is an important way to realize safe and efficient mining in fully mechanized caving face.
On the basis of the theoretical study of man-machine-environment system engineering, safety psychology and ergonomics, this paper analyzes the three system elements of personnel, machine and environment in fully mechanized caving face of coal mine, and finally selects 9 personnel-related indexes, 6 machine-related indexes and 7 environment-related indexes which affect the safe and efficient mining of coal face. The systematic characteristics of fully mechanized caving face are analyzed from the angles of theory, coupling theory and entropy theory. It is pointed out that the system fusion of fully mechanized caving face refers to the dynamic relationship among the three systems of man, machine and environment, which coordinate and promote each other. The aim is to realize the safe and efficient mining of fully mechanized caving face through the system fusion. The concepts of capacity coupling degree model and system coordination degree in physics are introduced. The man-machine-environment system fusion degree model is introduced. According to this model, the compatibility of 61B3 working face in a mine in Shanxi Province is evaluated and analyzed. According to the evaluation results, technical and management measures are put forward from three aspects of personnel, machinery and equipment, and environment. Finally, the phase is verified. The improvement of meltdown is conducive to the safety and efficiency of production.
