| 摘 要： | 数字矿床模型是指将传统的地质学语言描述的矿床特征，转化成计算机可以识别的数字和符号，并加入人工智能的推理规则和知识，使之具备矿床自动推理和勘查辅助决策的功能。本项研究是在基于前人的工作基础上，结合国内外数字矿床模型的先进理论和经验进行了系统的实现。本文论述了铜矿床数字化的方法原理以及在系统实现时的关键性技术问题。系统知识库和规则库的建立是在多位铜矿专家的协助下完成的，专家对一系列先验概率等相关参数进行赋值，并用统计学方法下进行了处理。铜矿专家系统中知识库和规则库的保存和管理使用了数据库开发技术，采用数据挖掘作为知识发现的新手段。系统使用产生式规则，采用主观贝叶斯方法为推理的总体算法，搜索策略采用广度优先向前搜索的策略；在地质证据的输入方面不只提供与铜矿类型直接相关的证据，同时系统也提供了更为充分的地质证据，使推理的过程更加可靠和合理，同时地质词典功能的加入方便用户对相关地质术语进行查询和检索。系统不仅能实现单一成因的矿床进行推理，也能对复合矿床类型进行推理。

| Abstract: | The digital deposit model is meant to transfer the deposit features described in traditional geological terms into the data and code that can be understood by computer and put AI knowledge and rules into computer so that the computer can reasoning automatically and assist geologists ,exploration companies to make decisions. The research is based on the achievement of the predecessors, combined with advanced theory and experience from domestic and abroad .The paper set forth the principle and method of digital copper deposit model and some key techniques in the implementation of the system. The knowledge and rules were built with the help of the copper geologists, who provided the parameters related to the reasoning such as pre probabilities, which were handled with statistics method. The database development skills were applied to store and manage the knowledge and the rules while the knowledge founding adopted data mining technology. The system use the production rules and adopt subjective Bays method as the algorism The search strategy is span priority and forward search. Different from the previous system which provided limited evidence only directly related with the copper deposit, the abundant evidence is offered for users to choose ,which lead to more reasonable and reliable conclusion .Moreover ,it has the function of geological dictionary ,which make the users more convenient to query and search. The system can not only infer solitary cause deposit, but also predict the complex causes deposit. The result presented in this paper reflect preliminary achievement of the project supported by Chinese High-Technology Research and Development(863) Program. |
