Thirdly, it analyzes and studies in detail Surpac mechanism and the relevant concepts on constructing the model of mineral deposits and mining engineering systems according to the modeling procedure and the actual conditions of Jinchuan"s mines. Based on these:Lit points out some differences between the western countries and China in the practice of the geological data record, explores the inputting data on computers performed by more people at the same time and the method to improve constructing the data-base and finished the data-base of Jinchuan mineral deposits;2.It puts forward the steps and flow chart to construct the solid model and brings forward the scheme of "first individual then whole to set up Jinchuan mineral deposits geological model, summarizes some experiences for constructing the complicated geological ore body of the high accuracy: add control lines, add auxiliary demarcation lines +control lines, the operation of intersection, cross and incorporation between solid bodies and plane and section combination. The above-mentioned methods applied to construct the mineral deposits solid models of four mine areas in Jinchuan; 3.lt studies and presents the detailed flow chart of constructing block and grade model, analyses the workable scheme in setting up the block and grade model of main ore body for Jinchuan mineral deposits and also sets it up.

接着，按建模流程并结合公司矿山实情，详细研究、分析了Surpac构造矿床模型和采矿工程系统模型的机理、有关概念，在此基础上：(1)指出了西方国家与我国在地质数据记录习惯方面存在的一些差异，探索出多人多机同时录入、提高建库效率的方法，建立了金川矿床地质数据库；(2)研究并提出了构造实体模型的步骤和流程图及&先分后整&建立金川矿床地质体实体模型方案，总结出建立高精度复杂地质体模型几点经验：添加控制线法、添加辅助分界线+控制线法、实体间的交、叉、并运算法及平剖面图联合法，建立了金川矿床四个矿区主矿体的实体模型；(3)研究并提出了建立块模型、品位模型详细流程图，分析了建立金川矿床主矿体块模型和品位模型的可行方案，建立了金川矿床主矿体的块模型和品位模型。
