Research On The Risk Control And Safety Training System Of Mines In China

Mining accidents accounted for about 36.2% in all kinds of security casualties in Chinese industrial, mining and trading enterprises. The frequent mining accidents have been the "bottleneck" of our national security production. Therefore, careful studies on the prevention and control of mining accidents have been carried out all over the world. However, previous studies were focused on the prevention and control of occupational hazards in mines. The research on the control of human behavior is relatively less, and the research combined the hazards control and safety training is rarely reported. Based on the above issues, the thesis is carried out to study the risk control, the safety training, and the training system construction in mines by theoretical analysis method.According to a comprehensive collection of the statistics of production safety casualty from 2002 to 2009 in China, the rules of the casualty accidents in mines have been analyzed by statistical method. Following relationships have been studied:the number of mine accidents in China and the development trend of the number of deaths, mining companies with different ownership and the number of mine accidents, the main types of accidents in mines, the relationship between the mine accidents with the months of the seasons in a year, and the causes of accidents in mines and some other issues. Some conclusions have been obtained in the research. The main occupational hazards in mines and the causes are analyzed by the theory of the accident causing method. The corresponding control measures and countermeasures have been put forward. These studies build a foundation for the mine risk control and the construction of safety training system.Major hazards of coal and non-coal underground mines are respectively identified and determined by using two kinds of hazard identification theory combined with statistical analysis of accidents. A hazard evaluation model by fuzzy mathematics in shaft hoisting system based on AHP method and an accident tree of gas burst are constructed based on two major hazard sources in mines as an example. The mathematical solution were counted, and the conclusions are consistent with the actual mine production. At the same time, the countermeasures to control the mining risk have been put forward according to the results of the evaluation model. These studies have clearly pointed out the main direction for hazard evaluation and control in mines. The theory provides a new way of thinking and new methods of production for the safety of mines. It has important significance in realizing the mining safety.According to the statistical analysis of the safety accidents in mines in China, it is found that the main cause of accidents in mines is human being. Based on the theory of security behavioral science, the influence factors on the unsafe behavior of human being, the unsafe behavior leading to major risks and the causes of unsafe behavior in mines are researched and analyzed. The effect of the unsafe behavior on the safety producing in mines is discussed. The control measures of humans'unsafe behavior have been put forward. From the perspective of safety training for mine employees, the focus of training contents have been proposed for managers and operators in mines. It is significant to do researches on the causes of human being for the construction of safety training system, the implementation of mine safety training, and the comprehensively improvement of the quality of employees in mines.Taking the safety training of coal mine as an example, the formation of mine safety training system has been studied. According to the role of mine safety training during the different period, the mine safety training process can be divided into six development stages in China. The safety training system of mines in China is analyzed. The specific meanings of national security classification management training institutions are researched. The distribution map of training organizations is drawn. The existing main problems of the training system are discussed. Various types of mine training contents and the assessment standards are summarized. The development and the common characteristics of several developed countries'safety training system are introduced. It can provide a good reference to construct an efficient training system and establish the mechanism of mine safety systems.The model of safety training system in mines has been basically constructed by studying the characteristics and the rules of safety training, combined with the mine safety producing features in our country. All the aspects of the control and operation process in the mine safety training are researched. The problems during the implementation of safety training are analyzed, and the improving methods are put forward in a training case for the principal responsible persons in metal and nonmetal mines at training institutions. The way to improve mine safety training efficiency and to make the corresponding countermeasures is analyzed by introducing the modern learning theory and the education, thinking of behavior science. Based on the concept of entropy in information theory, the quantitative calculation of the training quality has been carried out by fuzzy evaluation method in a case, and the conclusion is consistent with the actual state.In summary, this study has important theoretical and practical value for the prevention and control of risks in mines, for the construction of efficient and practical safety training system in mines, for the improvement of training methods and for the realization of the safety producing in mines.
