Abstract Mental fatigue increases risk-taking behavior. Using data collected between June 15 and August 6, 2020, this study investigates the impact of miners’ mental fatigue on risk decision-making to improve risk prevention and prediction abilities, and to reduce the occurrence of coal mine safety accidents. A total of 274 and 33 people participated in the preliminary and formal experiments, respectively. The participants, who were coal miners, visited the lab thrice to complete the pre-experiment, Balloon Analog Risk Task (BART), Iowa Gambling Task (IGT). On the BART, mental fatigue displayed a significantly positive association with risk preference. On the IGT, as mental fatigue increased, net scores continuously decreased, while the frequency of making unfavorable decisions and the probability of taking risks increased. The BART value had no or weak correlations with the net score. Results suggest that mental fatigue leads to an increasing propensity to take risks. Therefore, regarding coal mine safety management, further attention is necessary concerning miners’ mental health, addressing mental fatigue, increasing rest time, and reducing night work. Furthermore, reasonable diet, improved working environments, and a positive attitude toward work should be promoted to reduce or eliminate mental fatigue and avoid decision-making errors that could cause accidents.

The Impact

The main cause of coal mine safety accidents is the unsafe behavior of miners who are affected by their emotional state. Therefore, the implementation of effective emotional supervision is important for achieving the sustainable development of coal mining enterprises in China. Assuming rational players, a signaling game between miners (emotion-driven and judgement-driven) and managers is established from the perspective of Affective Events Theory in order to examine the impact of managers’ emotions on coal miners’ behavior; it analyzes the players’ strategy selections as well as the factors influencing the equilibrium states. The results show that the safety risk deposits paid by managers and the costs of emotion-driven miners disguising any negative emotions affect equilibrium. Under the separating equilibrium state, the emotional supervision system faces “the paradox of almost totally safe systems” and will be broken; the emotion-driven miners disguising any negative emotions will be permitted to work in the coal mine, creating a safety risk. Under the pooling equilibrium state, strong economic constraints, such as setting suitable safety risk deposits, may achieve effective emotional supervision of the miners, reducing the safety risk. The results are verified against a case study of the China Pingmei Shenma Group. Therefore, setting a suitable safety risk deposit to improve emotional supervision and creating punitive measures to prevent miners from disguising any negative emotions can reduce the number of coal mine safety accidents in China.

In order to make the coal exploitation to the healthy and sustainable development, the reasonable deployment of development of coal resources insist on shutting down before the integration, with the principle of the big merging into the small and the inferior merging into the superior. Coordinating to Hongfa coal mine and Luda coal mines In Ding Qi town. By integrating, it can achieve the goal of coal mine safety production and optimization of coal resources, and also can solve some problems left over by history. Through the analysis of local water resources development and utilization, we adopt the method of rainfall to inquire runoff volume and the frequency analysis to reason the results. The results show that either status quo of the level year or planning level years, Ma Daozi village gulley can completely meet the requirements of project for water, Water intake of water is reliable and the impact is not big to regional water resources.

Coal mine safety production is of great significance in China. Modern information management and network technology are used to establish a coal-based early warning emergency command information system. The system provides a fast and effective digital platform for the mine safety management and emergency response decision-making. The system's functional framework, operation process and some key algorithm of the system were introduced in the paper. The technology of System construction has also been mentioned.
