通过对单个工程矿体边界圈定规则的研究,采用二分法提出了一种能自动进行单工程矿体边界圈定的计算机算法.该方法利用计算机精度高、速度快的优势进行边界逼近,可以将原有按采样分段进行的离散圈定,变成连续圈定,可以替代以采样边界为圈定边界的固有模式.该方法应用于云南磷化集团某磷矿单个工程圈定,使储量计算的自动化程度有很大提高,对指导采矿生产具有一定意义.
Through the research on the rule of boundary delineation in a single project, a dichotomy method is proposed to automatically calculate the bound of a single-body ore body.The method uses the advantage of high precision and high speed of the computer to approximate the boundary, There are discrete delineation by sampling subdivision into continuous delineation, which can replace the sampling boundary for the delineation of the intrinsic mode of the boundary.The method is applied to a single engineering delineation of a phosphate rock in Yunnan Phosphate Group, which makes the calculation of reserves have a very high degree of automation Large increase, to guide the mining production has a certain significance.
