Abstract: The phenomenon of rock burst appears while deep mining in Sanshandao Gold Mine. The dangers of instability and roof collapse are induced by rock burst in production area, which requires monitoring and early warning. Based on the test results of micro seismic monitoring system for monitoring the safety of deep gold mining, the technical approaches of pre-warning for deep rock burst at deep zone are studied based on the seismic monitoring, including the forecast of dangerous rock burst zone, security level of the stope based on the micro seismic monitoring, micro seismic monitoring of water inrush etc. The monitoring and early warning of deep mining are achieved through the comprehensive monitoring of the rock steady state and dynamics of the target area.

Key words: Deep gold mine, Micro seismic monitoring, Early warning of rock burst
