Discussion on Some Topical Issues of Water Prevention and Control in Coal Mines

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