项目摘要

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.

考虑了一种集成系统的原型，该系统可以更合理地实现临近城区露天矿的进度模拟、采矿作业和产品评估。该系统还可以有效地正确和快速地响应环境保护等社会要求，以及交通运输沿线的交通畅通。在露天矿地形测量中，考虑卫星配置和矿山陡坡，采用实时运动学全球定位系统（RTK-GPS）。RTK-GPS快速为矿山地形监测提供了足够精度的数字地形数据，使地形数据的更新变得容易。从而实现了基于数字地形数据的地形图生成、地形图修改、矿山生产力估算和开挖景观模拟的计算机图形与数据库系统。此外，还对卫星光学传感器获取的露天矿图像和荧光法检测的微裂纹图像进行了分析。对某大型露天矿的GPS应用进行实地调查，有助于该系统的集成。如果将数字成像自动摄影测量系统与航空测量和RTK-GPS系统配合使用，可以提高采矿和数字测图的安全性。
