SURPAC软件在预测矽卡岩型盲小矿体中的应用

Application of SURPAC in predicting skarn type blind and small ore bodies

沂南金矿金龙矿区控矿构造为接触带构造,根据已有探采工程等资料,应用SURPAC软件提供的强大空间分析功能对地质信息进行整合,然后对接触带构造进行预测,最后利用坑内钻对预测出的接触带构造成矿效果进行验证。验证结果表明,在局部范围内应用SURPAC软件可以较为准确地圈定成矿预测区。

The ore-controlling structure of Jinlong mining district of Yinan Gold Mine is contact zone. According to known exploration and mining engineering data and on the basis of geological information integration with the help of strong spatial analysis function provided by SURPAC,the tectonics of contact zone is predicted. Then,the tectonic mineralization of the predicted contact zone is verified by the pit drill. The results show that the application of SURPAC can rather accurately delineate mineralization prediction areas in local scope.
