Abstract
Emergency management of coal mines requires enhanced synergy among departments, institutions, and enterprises, which means overall efficiency in management. Their synergy can effectively lower the cost of emergency management, improve the effectiveness of it, and build a strong joint force for the prevention and control of emergencies. Accordingly, this study established a synergy system for regional coal mine emergency management and analyzed the interest relationship among key stakeholders in the system. Then, it established differential game models of the management synergy, explored the selection process of the behavior strategy of each stakeholder under different situations, and provided important tools for quantitative analysis on emergency management synergy practice. Furthermore, numerical simulation was carried out to analyze the influencing factors of their decision behaviors. The research results are of great significance for the comprehension of the evolution mechanism for the emergency management synergy of coal mines, the assistance for the government in determining the optimal method in emergency management synergy, the mobilization of the stakeholders, and the improvement of the current situation of emergency management synergy of coal mines in China.
Highlights
With the rapid development of coal mine industry and the promoted awareness of emergency management, improvement has been made in mining safety and emergency management of coal mines in China
When a coal mine emergency (CME) occurs, the comprehensive improvement of CME prevention and control capacity requires a regional CME synergy mechanism to effectively coordinate the strengths of the government, relevant enterprises, and nongovernment entities. erefore, whether from the perspective of national-level design or from the actual operation situation of coal mine enterprises, researches on CME management synergy deserve more attention, which is of far-reaching significance for the establishment of a longterm mechanism for safe mining in China
When C2 > 0, the more the emergency efforts of each emergency subject pays, the higher the emergency cost for rough the emergency management synergy, the synergetic benefits obtained by the local government and functional departments and coal mine enterprises are, respectively, αcφ(t) and βcv(t), where α and β represent the benefits brought to the local government and enterprises per unit reduced accident loss
Summary
With the rapid development of coal mine industry and the promoted awareness of emergency management, improvement has been made in mining safety and emergency management of coal mines in China. Based on the connotation of synergy and previous research results, the concept of emergency management synergy is defined as follows: In order to prevent, control, and reduce accident losses, under the unified leadership of the government and relevant departments, the relevant subjects make rapid response in accordance with the synergy mechanism, make decisions scientifically, and fully share and optimize various resources in the emergency management to deal with the accidents or process of emergencies. An analysis on the current situation of emergency management synergy in China and international community reveals that China just started to explore the emergency management synergy mechanism and yielded relatively few results, especially those about coal mines. The emergency management synergy mechanism deserves more researches, and few researches were conducted on the game analysis on the dynamic behavior evolution of each subject in the system. erefore, this study introduces the game theory to the CME management synergy mechanism to explore the evolutionary game behavior and synergy relationship among the CME management subjects and is aimed at guiding the establishment of the regional CME system and improving the emergency management synergy ability of these subjects
