Abstract:

A new method of Open-pit Topography and Geology Integrated Solid Models dynamic update was put forward based on surface mining character. In this method, the topography and open pit field models local update in extended boundaries was realized by seamless splicing between New Tins and Old Tins. And the geology solid model was composed of stratum and geologic bodies’ models, which were reconstructed by re-interpolated Points based on new adding reality points. After that Open-pit integrated solid model updated was come true by Boolean coupled operation each other. The application case shows that this method is fast, effective, stable and operable. And it can satisfy the need of integrated solid model dynamic accuracy in mining design and engineering management.
