| 摘 要： | 插值计算是矿产储量计算中的重要环节，但由于计算量大，经常需要在插值密度和计算时间之间进行权衡。本项研究通过最新的CUDA技术，将插值运算转换到显卡上进行并行化计算，极大地提高了计算速度。以紫金山铜矿数据为研究对象，进行了方法技术的实验，与基于CPU的计算相比，基于GPU下CUDA的计算速度提高了67倍。

| Abstract: | Interpolation is playing an important role in evaluation of mineral reserves, and is also an overwhelming computation that makes it needed to find a tradeoff between the density of interpolating and the time of calculating. The research is taken to move the interpolation from CPU to graphic card by means of CUDA, and has improved much the speed of the calculation. An experiment on evaluation the Zijinshan copper mine data showed the merit, and a result of acceleration of 67 times was achieved by compared the calculations of CPU based and GPU based. |
