Karst water is one of the major water hazards in China coalmines, causing frequent mine flooding and sever human casualties. This article, starting out on the spatial relation between mining facility and karst aquifer, extensively illustrates the techniques to identify water burst risks in karst aquifer and field testing methods of key parameters; primary water hazards control techniques for specific mining conditions and hydrogeological properties, such as retaining water-resistant safety rock pillar, water draining and depressurizing, bottom aquifuge consolidation grouting and revamp. All achievements can be of reference to other coal-producing countries confronted with karst water hazards.
