Abstract: Based on the characters of occurrence and mining method in metal mine, the pressure behavior of metal mine exploit was analyzed, and then the implementation principles suit for metal mining ground pressure monitoring and warning system were presented.Taken the Chengchao Iron as an engineering background, the monitoring system consists of stope stress, roof separation and tunnel convergence.In order to achieve comprehensive security monitoring metal mine pressure activity, many research methods were adopted, such as geological conditions of the ore body, rock mechanics test, mining history, three-dimensional simulation, monitoring information of ground pressure.

Key words: Metal mine, Ground pressure monitoring, Real-time warning, Combined analysis
