| Research Abstract |
A prototype of integrated system which enables more reasonable schedule simulation, mining operation and product estimation in open pit mines adjacent to urban zones was considered. This system is also effective for proper and quick response to social requirements such as environmental preservation and smooth traffics along the transportation route.
For topographic survey in open pit mines, Real Time Kinematic Global Positioning System (RTK-GPS) was adopted with considering satellite configuration and steep slopes in mines. RTK-GPS quickly provided digital topographic data of enough precision for topographic monitoring of mines, so that it becomes easy to update topographic data. Thus, computer graphics and data base system for topographic maps generation, modification of maps, estimation of mine productivity and simulation of excavated landscapes were realized based on the digital topographic data. Furthermore, image analysis of an open pit mine obtained by optical sensor on a satellite and of microcrack images detected by fluorescent approach were examined. Field survey on GPS application in an large open pit mine is helpful to integrate this system. For more safety mining and digital mapping, automatic photogrammetry system with digital imaging is useful, if it is adopted together with air survey and RTK-GPS.
