逻辑信息优化法在贵州大厂锑矿老采区找矿预测中的应用

Application of An Optimized Logical information Method To The Old Mining Area of Dachang Antimony Deposit, Guizhou Province

在分析大厂锑矿田成矿地质特征的基础上,应用优化逻辑信息法筛选地质标志,建立三态变量逻辑信息模型,对大厂矿床老采区进行综合成矿预测,在指出的3个成矿有望单元中。经过矿山工程验证已取得初步成效。此方法可在大厂矿田其它矿床中广泛使用。

On the basis of the analysis of geological features of Dachang Sb orefield, the writers applied an optimized logical information method to choose geological variables, establish a three-form logical information model and make a synthetical ore-forming prospecting in the old mining area of Dachang ore deposit. In the meanwhile, three promising ore-forming units were pointed out and some preliminary fruits have been attained through the test of mining engineering. This pros pecting method can widely be applied to other oredeposits of Dachang orefield.
