Abstract: With the development of science and technology, GPS(Global position system) has been widely applied to in open-pit mine measurement acceptance,slope monitoring. The slop GPS dynamic monitoring and warming system based on GPS and wireless communication technology and visualization technology play a crucial role in open-pit mine production safety. Based on the slop GPS dynamic monitoring and warming system, the slop monitoring visualization analysis system is developed combining the mathematical statistics and 3D visualization technology. The research results proved that, the slop monitoring visualization analysis system improve the effect of GPS monitoring data of open-pit mine slope, enrich the monitoring methos and have the great popularization significance.

Key words: Slop monitoring, Global position system, Digital terrain model, Visualization, Power distance
