隐伏矿体预测研究

Research on prognosis of concealed ore body

隐伏矿体预测,具有大比例、小尺度和高精度的特点。预测理论有相似类比理论、矿床模型理论以及地质异常理论、成矿系列和成矿系统理论等。预测技术方法有经验类比法,地球化学方法(如地气法、活动态偏提取技术),地球物理方法(如放射性测量、地面电磁法、地震法和井中物探),以及遥感技术、GIS技术和综合信息矿产预测方法等。拓展找矿思路、加大深部找矿力度、多学科合作、应用新技术和新方法是今后隐伏矿体预测的发展趋势。

The prognosis of concealed ore body is characterized by the large scale, small region and highprecision. The predication theories include of similar analogy, ore deposit model, geo-anomaly, deposit metallogenic series and metallogenic system. The predication technical methods consist of experience-analogy, geochemical techniques （e.g. geo-gas method and partial extraction of mobile forms）, geophysical techniques （e.g. radioactivity survey, ground electromagnetism, earthquake technique, hole geophysical survey）, remote sensing, GIS, and comprehensive information prognosis methods. The developing trends of prognosis of concealed ore body in future appear to include extending ore-search thinking, enhancing ore-search depth, more subjects＇ cooperation and using new techniques and methods.
