摘　　要：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.This article studies the rule of demarkating border of single engineering mine, introduce dichotomy and proposes a computer counting way which can automatically demarkate border of single engineering mine. The method＇s boundary approach uses the advantage of the computer＇s high precision and high speed, which can change the disperse rope by intrinsic sampling subsection to continuous rope, which breaks the inherent pattern of using the sampling boundary as the roping boundary. Proved by experiment of Yunnan Group of Phosphorus Chemical Industry, the demarcating result is meaningful for guiding mining production, which highly improved the automation degree of the estimation of mineral resource reserves.
