| 摘 要： | 本文研究了当前正在发展的立体定量预测中的地质几何方法的基本原理和数学模型及其应用。作者采用多项式函数和趋势-剩余分析对控矿地质界面(如地层界面、不整合面、断裂面及侵入接触界面等)进行形态模拟,并根据模拟所得地质几何参数对矿体进行空间定位和深边部立体预测,然后采用三维趋势分析或克里金法对预测地段的矿床值进行定量估计。四个矿床的预测应用证明该方法实际效果较好。

| Abstract: | This paper studied the basical principle and mathematic models of geological-geometric methodin three dimension prognosis. Authors made shape-simulation of ore-controlling geological interface(such as strata surfaces, unconformity planes, fault planes and intrusive-contact surfaces, etc.) usingpolynomial function and trend-residue analysis, pelformed spatial loealition and localizing prognosisfor ore bodies according to the geological-geometric parameters gained from simulation, and thenestimated ore deposit value by three dimension prognostical model. The practical effect is good inthe prognosis application in four ore deposits. |
