摘要
近年来许多老矿山的保有资源量日趋减少,随着开采的不断深入,保有储量已难维持矿山日常生产,而针对这些矿山的勘探资料充分和数据量大的特点,可以借助G IS的强大的空间分析技术,以计算机为辅助工具,对老矿山的周围和深部进行成矿预测研究。M APG IS在空间分析方面提供了强大的空间分析模块——DTM分析。笔者以广西大厂锡矿为例,采用M APG IS软件,利用其DTM功能,从建立矿体的矿化强度模型入手,对矿山的周围进行了成矿预测研究。文章认为:运用G IS的空间分析技术进行成矿预测是今后几年内进行成矿预测研究的一个重要发展方向。
The retained mineral resources in many old mine have been reducing every year. With the mining going further the retained reserves is hard to maintain the routine operation in mines. The vast data of prospecting in these mines however, enable us to carry out ore forecasting in the surrounding areas and deep part of the old mines aided with computer and advanced special analysis technology of GIS. MAPGIS provides a strong special analysis module, namely DTM analysis, in the aspect of special analysis. Taking the Dachang tin deposit of Guangxi as an example, using MAGIS software and its DTM function, starting from setting up mineralization strength, the authors have carried out ore prediction surrounding the mines. It is believed that ore prediction with GIS special analysis technology will be a very important orientation for ore prediction research in near future.
