Study On The Personnel’s Safety Evacuation In The Underground Mine Fire Of The Non Conventional 4D Time

In recent years, with the rapid development of the mine industry, the degree of danger of underground mine fire has been increasing. The fire bursting in the mine will not only cause a large number of the destruction and of frozen of coal mine equipment and resources, but also make the personnel’s life health face serious threats. Personnel’s security evacuation in underground mine is one of the core issues of unexpected events of public safety, about which the research of this problem has high theoretical and practical value.In this report, the personnel’s safety evacuation of non conventional bursting fire in the underground mine is regarded as the research object to analyze the mechanism of the evolution of fire in underground mine, in order to establish the evolution model and the spread model of fire based on the theory of complex network and fire. Then, the mechanism of personnel’s safety evacuation in underground mine is studied to purpose the behavior decision model of the interval valued intuitionistic fuzzy multiple attribute security evacuation based on the prospect theory. Next, safety evacuation mechanism in fire bursting situations of underground mine is explored to establish the safety evacuation model based on the multi intelligence system. Based on the above theoretical research, the safety evacuation simulation system of the underground mine is established. Last, LNXHS, underground mine is regarded as an example to do the simulation and the empirical analysis, in order to verify the feasibility of the theory and model of this study. The main projects and findings are as follows:(1) The spread mechanism of underground mine fire is studied, and the process of the occurrence and development of underground mine fire is analyzed. Then, its spread characteristics are analyzed through the process and approaches of the fire spreading. Next, based on the complex network theory, the analysis method of the social network is employed to do model and analysis to the influential factors of the complex network of the underground mine fire, in order to obtain the relationship between the factors importantly affecting the fire network and the factors of the fire. Finally, the modeling method of small world network is used to construct the spread effect model of the underground mine fire.(2) Based on the theory of psychological stress, personal psychological deviation and risk perceiving theory in psychology, this report focuses on studying especial physiological and physiological response characteristics of evacuation personnel and analyzing the characteristics of leadership behavior and group in the context of underground mine fire. The factors of decision making influencing the safety evacuation of the underground mine are proposed and the decision-making model of the safety evacuation behavior is build based on the fuzzy multiple attribute of interval valuing intuitionistic of prospect theory. This model can explain the safety evacuation decision behavior of makers in the complex system of underground mine fire, because of uncertainty environment, incomplete information, and personal psychological behavior and multi attribute factors.(3) The factors of safety evacuation in the context of underground mine fire include 5 influential factors: environment of underground mine and fire, human factors, evacuation time, and fire emergency management system. The principle of key factors is explored, which affect the safety evacuation of the underground mine. The behavior structure and the model of Multi-Agent System based on the decision-making process are proposed and an interaction model based on decision multi-agent arbitration mechanism is established.(4) The safety evacuation simulation system of the personnel of the underground mine is established based on the OGRE engine, which can provide3 D scene modeling of underground mine, dynamic spread of flame and smoke and technical support of Multi-Agent simulation. Furthermore, the 4D spatial data model is established to support the 4D spatial data combing 3D scene layout of the underground mine fire, the simulation characteristics in time and space dimensions. The establishment of the system can provide not only the good support for the theory and model of this study but also have an important practical significance to evacuation safety assessment and safety education of the personnel in the preventing fire design of the underground mine.
