煤礦險(xiǎn)兆事件管理模式研究
[Abstract]:Safety management is an important part of coal mine management. Therefore, studying the management mode of coal mine risk precursor event is beneficial to provide theoretical guidance for coal mine risk precursor event management. Firstly, using Hall three-dimensional structure theory, taking the management object, management procedure, knowledge and skill as the dimension, this paper puts forward the Hall three-dimensional model of coal mine risk precursor event, and carries out the daily management of the risk and precursor event from the micro level. Among them, eight scale factors of program dimension and four scale factors of object dimension are determined by the method of literature review, and the eight scale factors of knowledge and skill dimension are determined by exploratory factor analysis of questionnaire data with SPSS20.0. In addition, the RDF cycle is taken as the operating mechanism in the Hall three-dimensional model of coal mine risk precursor event. Based on the model, the time dimension is added to form a four-dimensional management model of coal mine risk precursor event. Then, in view of the actual operation and application of the management mode of risk and precursor events, this paper takes fully mechanized mining face as an example, analyzes the relevant identification methods according to the category of dangerous and precursor events, as well as the management procedures such as reporting, measures, rectification, feedback and so on. Secondly, the fuzzy comprehensive evaluation model of coal mine risk management is constructed. According to the three dimensional model of Hall, the evaluation index system of 3 kinds of 20 factors for the management of coal mine dangerous events is established. The membership degree of fuzzy evaluation index is obtained by Delphi questionnaire, the weight of each evaluation index is determined by AHP, and the evaluation conclusion is obtained by multistage fuzzy comprehensive evaluation method. The results show that the fuzzy comprehensive evaluation model has reliability and practicability, and it is of great significance for coal mine risk management. The study on the management mode of coal mine risk omen event is not only beneficial to enrich the theory of coal mine risk management, but also in line with the development trend of safety management in the current dual system construction of risk and hidden danger.
