差分GPS在矿体勘查中的应用

物探仪器与高精度GPS技术的结合,是当今物探工作的一个趋势.为了更好的为地质、地球物理找矿快速评价工作服务,野外使用亚米级精度Trimble Pro XRS差分GPS为物探测点定位,实现了物探测点实时精确定位,为物探空间定位分析提供了可靠保障.此外,可以利用差分 GPS绘制地形、地质简图,记录特殊地物,为物探数据解译、工程调整提供依据.实践表明,差分 GPS可以有效的为地质、地球物理快速找矿评价工作服务.

Application of differential GPS in location forecasting of ore

The physical prospecting instrument combined with high precise GPS is now a physical prospecting work tendency. In order to serve the geological and geophysical prospecting and assessment better, we use decimeter differential GPS (Trimble Pro XRS) to determine position of the geophysical prospecting measuring point, and we can acquire the real-time precise GPS measuring point of geophysical prospecting. The measuring point had provided reliable guarantee for the geophysical space orientation. In addition, we can use the differential GPS to draw simple topographical map and geological map and to record some special objects. These works can provide the basis for the geophysical prospecting data interpretation and the project adjustment. The practice indicated that differential GPS can serve the geological and geophysical prospecting and assessment effectively.
