There exists a high risk of water-inrush in mining activities. Therefore, it is critical to develop a conceptual model of Mine Water-inrush, especially for the underground environment. The general structure of Mine Water-inrush Simulation System consists of core network, the underground monitoring network, and the operational system. Through the application of data processing system, simulation system and the application system, the original data can be processed. The results is then passed to the operators and managers, which require them increase the understanding of factors leading to accidents and consequently take action to improve mining safety. This new water-inrush model captures three characteristics to regard the mine water-inrush: the inrush sources, inrush process, and submerging process. Virtual length has been applied to the model, which is combined with a Traversal Algorithm, can be used to calculate the area of increased influence over time for each process. Based on the collected data from a real mine, the underground excavations and a virtual water-inrush disaster process were simulated, which shows that the system operates reliably.

The paper aims at presenting an organizational social responsibility approach for improving mine safety and health in China. Through an in-depth comparative analysis of the regulatory mechanisms for mine safety and health in USA and South Africa, it is found that the successful performance of mine safety and health in USA has been contributed by the triangle of effective law enforcement, advanced technology development and qualified labor training, and the impressive improvement of mine health and safety in South Africa has been attributed to the mechanism of tripartite engagement through the state, mine owners and employees. In view of findings from the US and South Africa experiences, an approach of organizational social responsibility through multi-stakeholders is proposed for China to fundamentally improve its performance of mine safety and health by adopting best practices.
