Effective prevention and control of water hazards in China’s coal mines require that several key issues be addressed. The key issues discussed in this paper are the complex and variable water inrush types in mines, uncertainties in calculation of mine inflow, and the primary mechanism of water hazards resulting from mining-induced bedding separation. Challenges encountered in reinforcement and grouting of the seam roof and floor are also discussed, as well as the risks posed by mine closure. We suggest research areas to better predict and understand the impacts of these issues and propose a direction for improvement of coal mine water control.
