Research on Application of Hydraulic Fracturing Enhanced Technology in Coal Mine

Coal and gas outburst accident is one of the critical disasters restricting the safety production of coal enterprises in China.

Research on Safety Regulation of Chemical Enterprise under Third-Party Mechanism: An Evolutionary Approach

In recent years, China’s chemical industry has incurred frequent safety accidents which seriously impact the social environment and public safety. Traditional approaches have reached a bottleneck due to a lack of relevant professionals in the government regulation of chemical enterprise safety production. Thus, a new safety regulation mechanism should be conducted. In this paper, we constructed an evolutionary game model of chemical industry safety regulation based on limited rationality, and the influence of main parameters on the equilibrium evolution process is studied by system dynamics simulation. The results show that government regulation authorities play a leading role in the process of chemical industry safety regulation and increasing punishment will help to achieve an evolutionary stable strategy (ESS). What is more, the feasibility and effectiveness of the third-party regulation service mechanism are verified, and the market access threshold of third-party regulation service needs to be improved to stop the occurrence of rent-seeking activities in the regulatory process. In summary, the introduction of third-party regulation service entities to the chemical industry safety regulation process has far-reaching implications for promoting the healthy development of China’s chemical industry.

Evaluation of Chinese Enterprise Safety Production Resilience Based on a Combined Gray Relevancy and BP Neural Network Model

Improving the resilience of enterprise safety production is one of the important ways to deal with the frequency of safety accidents. Based on the definition of enterprise safety production resilience, we fully consider the impacts of recovery resilience, self-organizing resilience, and learning resilience as the three dimensions of enterprise safety production resilience. We build a back propagation (BP) neural network model that analyzes the main factors of enterprise safety production resilience using the results of gray relational analysis as an input that can assess the resilience of enterprise safety production and provide a valuable reference for the improvement of an enterprise’s safety production level. The results show that the resilience of production safety obviously increased after the Chinese enterprises with low resilience (as predicted by the model) adopted the corresponding early warning methods. The gray relational degree analysis method can incorporate well the variables for the establishment of the BP neural network prediction model.

Game Research on Coal Mine Workers’ Off‐Post Behaviors

In order to seek for causes and solutions of off‐post behaviors of coal miners, static and evolutionary games were utilized on the basis of an established strategy simulation model between coal mine enterprise and coal miners. These games were used to determine the revenue matrix of two game parties given off‐post behaviors of coal miners from two levels (coal miners and coal mine enterprise). Thus, equilibrium and dynamic evolutionary analyses of the two parties should be conducted. Results indicated that, in the enterprise’s perspective, inspection cost and punishment intensity are important factors that influence the safety production and economic benefit of coal mine enterprises; in the coal miners’ perspective, wage loss and the constraint degree it generates are essential factors. Furthermore, these factors constitute a key to solving off‐post behaviors of coal miners. Reasonability of the established simulation model was analyzed and verified on the basis of off‐post behaviors of workers from a coal mine that belongs to Yanzhou Coal Mining Co., Ltd. The coal mine enterprise should enhance the inspection of safety production and establish scientific and complete off‐post punishment mechanism. Moreover, the coal mine enterprise should provide proper compensation, treatment, and reward policies of workers to reduce the off‐post behaviors of workers from a coal mine enterprise effectively.
