矿床或矿产远景区的查明往往归功于区域物化探异常。这种异常尽管只含单个异常点也不应当忽视。使用密的测线不一定是可取的,需要权衡勘查费用与被查目标的价值。在制定勘查战略中涉及的一个问题是测线切割目标的概率估计。已有的报导只讨论线状或椭圆状的单目标。本文中作者讨论了以多边形表示的任意形态的多目标情况并使用解析,数值积分以及蒙特卡罗法以对比结果。设计了FORTRAN程序并在IBM－PCXT微机上运行了考核用的例子(复杂形态的单目标与8个目标)。当目标定位不是均匀分布时,蒙特卡罗法将更为适用。
The discovery of the deposit or mineral prospect is often attributed to regional geochemical anomalies. This anomaly should not be overlooked, although it contains only a single anomaly. It is not always advisable to use a dense survey line, and the cost of exploration and the value of the target under investigation need to be weighed. One of the issues involved in developing a survey strategy is the probability estimate of the line cutting objective. Existing reports only deal with linear or oval single targets. In this paper, the author discusses the multi-objective situation of any shape in polygons and uses parsing, numerical integration and Monte Carlo method to compare the results. FORTRAN was designed and run on a IBM-PCXT microcomputer for evaluation purposes (single and 8 targets in complex form). The Monte-Carlo method will be more suitable when the target location is not evenly distributed.
