GPS MONITORING OF GROUND MOVEMENT AND MECHANISM OF UNDERGROUND MINING INFLUENCE IN JINCHUAN MINE

According to the established GPS monitoring system in Jinchuan No.2 mine, and the real-time monitoring of the ground movement induced by underground mining, the ground movement and deformation characteristics is analyzed according to the large amounts of monitoring data between 2001 and 2006.Based on this, the general transmission mode and presentation attributes of rock movement induced by mining the rapid incline metal mine is expatiated and the mechanism of ground movement is analyzed combined with the numerical simulation and the GPS monitoring results, meanwhile the developmental characters of ground movement velocity is discussed.
