Research On The Safety Culture System Of Coal Mine Enterprises

Safety culture in coal mining enterprises constitutes a significant part of safety management in coal mining. At present, the national safety situation in coal mining is rather complicated. In current condition, what are the influencing factors and formation mechanism of the safety culture system in coal mining enterprises? How do we judge objectively the safety culture level in coal mining enterprises? How do we evaluate reasonably the safety culture in coal mining enterprise according to the result of measurement? All of these questions are major issues requiring immediate solution.Based on the analysis of the logical connection between some relevant concepts, this thesis defines the essence of safety culture system in coal mining enterprises, pointing out that safety culture in coal mining enterprises aims at minimizing accidents and ensuring safety production. On a regular basis, safety culture is formed gradually or intentionally in the process of production, which embodies such unanimously accepted factors as safety production value, safety concept, some related safety production system, safety production code, safety production means and materials with distinctive features. It is the core of the operation and production in coal mining enterprises and concentrates on the concept culture. Orienting from this concept culture, safety culture exerts its influence on behavior culture, system culture and material culture, thus achieving an all-round and three-dimensional harmonious management of safety production in coal mining enterprises.Based on the theoretical analysis, this thesis takes Shenhua Mining Group and Xuzhou Mining Group as samples, explores their influencing factors by employing multiple regression and factor analysis, and arrives at the following conclusion: staff safety, safety awareness, social safety values, communication systems, social safety, education and training systems, safety accidents, industry characteristics, the national safety laws and regulations, management participation, incentive systems, organizational commitment, productivity levels of development, socio-economic and cultural safety of the cultural system of coal mining enterprises have a positive impact on the safety culture system in coal mining enterprises, which effectiveness is respectively 0.7147,0.6458,0.6692,0.713,0.7150,0.6975,0.5226,0.5034,0.5614,0.6290,0.5517,0.6505,0.6728 and 0.5716;and that authorized employees of safety culture system in coal mining enterprises have no significant effect. Based on control theory and self-organization theory, this thesis studies the formation mechanism of safety culture in coal mining enterprises, analyzes the constituent elements that contribute to the safety culture and their inter-relationship, and probes into the formation mechanism of safety culture in coal mining enterprises. The conclusion is: the core of safety culture evolution in coal mining enterprises is the concept culture; the fundamental difference between mandatory evolution and natural evolution is the evolution of safety concept system and the improvement of safety concept level. Centering on the safety concept level, such levels as safety system level, safety behavior level and safety material level exert influences to one another, so as to enhance the safety culture level in coal mining enterprises.Based on the research of influencing factors, by simulating the system dynamics modeling, this thesis discovers that the higher the safety culture level is, the greater the difficulty is to further enhance itself. To illustrate, within the same period, the improvement of material safety level ranks the easiest factor among the four elements that contribute to the safety culture level. Safety system level and safety behavior level rank the second, and safety concept level proves out to be the hard nut. After regulating safety concept level to a higher degree, such factors as safety culture level, safety concept level, safety system level and safety material level all gain a chance to enhance them during the initial period. After the organizational commitment and the managerial embeddedness of the enterprises involves in, safety culture level, safety system level and safety material level all gain a boom within a short period. In view of this, the construction of safety culture in coal mining enterprises needs to consider how to emphasize the influence of safety concept level among enterprise management and how to enhance the organizational commitment and the managerial embeddedness of the enterprises, so as to guarantee the improvement of safety culture level in coal mining enterprises within a short period. Moreover, it also needs to establish a set of practical long-term mechanism to promote the continuous improvement of safety culture.The continuous operation of safety culture system in coal mining enterprises requires support and protection from both inside and outside. From the outside, it needs to emphasize government supervision and to strengthen expert advisory system; from the inside, it needs to construct human resource management system which targets at safety culture and PDCA system that helps the operation of safety culture system. In addition, it needs to establish responsibility system and integrity system for coal mining safety, so as to ensure the continuous and smooth operation of safety culture system in coal mining enterprises, thus promoting the long-term development of these enterprises. Moreover, judging objectively the safety culture level in coal mining enterprises will exert profound influence on the discovery of inadequacy and continuous improvement of safety culture system construction. Based on this, this thesis constructs the evaluation system of safety culture level in coal mining enterprises by following the systematic and guiding principles, which weighs the importance of each standard by employing analytic network process, thus arriving at the assessment standards concerning safety culture level in coal mining enterprises. More specifically, when the total score is above 0.95, it belongs to the fifth grade as well as the highest grade, which means the safety culture should be maintained. When the total score is between 0.85-0.95, it belongs to the fourth grade, which means the safety grade is relatively high and safety culture has room to be improved. When the total score is between 0.75-0.85, it belongs to the third grade, which means the safety grade is medium and requires improvement. When the total score is between 0.60-0.75, it belongs to the second grade, which means a relatively low grade and safety culture wants development. When the total score is below 0.6, it belongs to the first grade of safety culture, which means it is the lowest grade and safety culture needs desperately an improvement.In order to define the effectiveness and operational practice of safety culture system in coal mining enterprises, this thesis sets safety culture evaluation as its foundation, contrasting Zhangshuanglou Mine and Jiahe Mine of Xuzhou Mining Group; it compares from the overall level of safety culture within the two mines, the evaluation of safety culture level of one's enterprise from staff with different posts, the evaluation of safety culture level from different parties within one coal mining enterprise, arriving at the following conclusion: the safety culture level of Zhangshuanglou Mine is relatively higher, which belongs to the medium level in the operation of safety culture; the safety culture level of Jiahe Mine is relatively lower, which belongs to the lower level in the operation of safety culture. Consequently, this thesis suggests that Zhangshuanglou Mine enhance its safety culture level from two aspects, namely, improving safety system level and safety material level as well as stressing safety concept construction; it also suggests that Jiahe Mine improve its organizational commitment, education training, reward and punishment system, thus improving its safety management level, infrastructure and hardware environment, so as to enhance its safety culture level.
