抄録

Utilization of digital topographic data for open pit mines was analyzed, including topographic map generation, modification of maps and estimation of mine productivity. On previous topographic maps of open-pit mines generated by computer systems, construction details, such as working faces and roads, were difficult to identify from the contour lines. In these maps, many contour lines were drawn very close together due to large fluctuations in topographic features. The presence of large numbers of contour lines often obstructed construction details. To identify these construction details, the outlines of each construction were drawn, and the contour lines enclosed by these outlines were erased. Furthermore, construction details, such as manufacturing plants and office buildings, which were not identified by the contour lines, were drawn using the same algorithm. Highly detailed maps that distinguished these construction details from contour lines were then created. This digital topographic data was useful for simulating scene changes and the extent of mining. Computer graphics allowed simulation of scene changes in advance, and provided basic data concerning future changes. Moreover, these maps allowed accurate estimates of mine production to be calculated. To generate these maps, GPS (Global Positioning System) was utilized to measure topographic changes only where the operations had taken place. Furthermore, construction detail outlines were also obtained from the operator's input previously arranged by the rule, i.e. inputting a set of surveyed points for construction. This mapping system easily maintained monthly or annually updated data on topographic and construction changes. For production schedule simulation, topographic maps, computer graphics, and product estimations based on monthly or annually up-to-date digital topographic data were useful.
