Study on the opencast landslide monitoring and warning methods based on the GPS, RS and GIS technology

On the basis of a systematical analysis of the Landslide causes and process, the thesis proposed a new opencast landslide monitoring and warning method, which adopts Global Positioning System technology (GPS) to acquire real-time and precision data of the mining area, applies remote Sensing Technology (RS) to receive mining area rock information and analyze the characteristics of the surface coverage, makes use of the powerful space analysis capabilities and performance capacity of the Geographic Information System (GIS) to analyze the many factors induced landslides and the nonlinear relationship between them. Modeling according to the mechanism of internal and external factors of opencast landslide, the method can monitor and warn opencast landslide disaster efficiently, accurately, and timely. Thus it is to play a greater role in disaster prevention and mitigation in the world opencast process.
