【摘要】 矿产勘查已进入信息找矿的新时代，新的探测技术、测试技术和信息处理技术为矿床定量预测提供了新的技术支撑。而GIS作为一种空间信息处理技术，以其无可比拟的优势，在地学数据处理和分析上得到广泛的应用。 本文重点研究了如何将GIS技术引入矿山基地深部及周边隐伏矿床(体)定位预测的问题。论文中以凤凰山矿区为实例，在充分考虑研究区地质背景的基础上，论证了进行信息特征分析的方法；以及对多元数据进行多源集成的方法和途径；讨论了应用模型的选择原则和方法，建立了研究区成矿预测的应用模型。然后，以上述研究为基础，汲取了当前软件设计的新思想，运用先进的开发工具，进行了大比例尺成矿预测地理信息系统的开发与实现。并运用该系统对研究区进行了检验，证明了该方法的有效性。 通过研究，本文取得如下成果： 1．解决了在矿山基地深部及周边隐伏矿床(体)定位预测引入GIS技术的有关方法和技术问题。为矿床预测的定量化和信息化提供了强大工具。 2．通过对实例的研究，提出了进行多元信息特征分析的方法。为信息的集成打下了基础。 3．对多元信息的多源集成提出了可行的解决方案。以凤凰山为实例，总结了GIS的多源信息集成的方法、流程、内容等。 4．针对所选的实例，建立了相应的应用模型。 5．按照程序与数据分离、图形数据和属性数据分开两大原则，使用面向对象的方法，采用组件技术和混合编程开发了大比例尺成矿预测地理信息系统。更多还原

【Abstract】 The era in which we live has been described as the age of information orefinding in terms of mineral exploration.New exploring,testing and information-treating technologies give support to the quantitative orefinding.GIS, as a spatial-information-treating technology, is widely used in treating and analyzing geodata.The emphasis was put on How to use GIS in prospecting blind deposits(or orebody) in the depth or about a mine in the research. Firstly,the methods were given to how to conduct characteristic analysis of the information about the given area which was selected as an example;then the methods and steps to integrating the data of multisource were studied; The rules of selecting an applied mathematical model were discussed.;And then a mathematical model was established for the given area. Based on the research done before an applied GIS for larg-scaled minerals prospecting was developed with advanced tool. Lastly,the developed system was proved good through field-test.The following achievements have been made by studying information related to the sample area.1 .The methods and technologies were given to how to introduce GIS into the positioning prospecting of blind deposits(or orebody) in the depth or about a mine.Therefore a powerful tool are provided for quantification and informatization of the positioning prospecting of blind deposits(or orebody).2.The method to how to conduct characteristic analysis of information from multiple sources was put forward.The solid foundation has been set for prospective successive research.3.A solution to integrating information from different variables and multiple sources was delivered. The ways ,methods and contents of integrating information from multiple sources were discussed4.A applied mathematical model was put up which was fit for the given example and similar conditions.5.Abiding by the two rules of code and data being separate and also spatial data and attribute data being separate,making use ofobject-oriented method, an applied GIS for larg-scaled minerals prospecting was developed and realized with the COM and mixed programming technology.更多还原
