【摘要】 本文是云南省省院省校科技合作项目“个旧锡矿深部利外围成矿预测及矿山增储研究”(2000YK—5)成果的一部分，侧重于论述个旧锡多金属超大型矿区高松矿田的矿产资源预测问题。主要应用信息论、时空序列、复杂性等理论方法对个旧锡矿地质、物探、化探、遥感等信息进行分析、提取和综合，并初步建立了综合矿产资源信息分析与预测系统，使用该系统在高松矿田圈定了3级共18个预测区，其中一个靶区已开始了工程验证，效果较好，达到了预期目的。 个旧锡多金属超大型矿区是我国和世界重要的锡产地，至今已有2000余年的开采历史，特别是经过解放后大规模的开采，现在资源危机非常严重，急需寻找新的资源。而高松矿田是个旧矿区目前工作程度较低的区域，仅在矿田中部北段开采10号矿群，但自解放以来该区域积累了一定的地质和物化探资料及少量的钻孔资料，再加上本次做的一些工作，基本可以满足综合矿产资源信息分析与预测的需要。因此本文将主要研究个旧矿区高松矿田的矿产预测问题。 由于任何单一的一种矿产资源信息都不能确切的指示矿产资源的存在，而多种信息的综合则可以较好的指示矿产资源的存在，因此应用综合信息进行矿产资源预测可以取得更好的效果。综合信息矿产资源预测在我国有许多有益的尝试，并且也取得了一些成果，但由于地学信息的多样性、间接性、随机性等特点，使得传统数据处理技术难以有显著作为。因而本文结合高松矿田实际情况，对信息论、时空序列、复杂性等非确定性分析方法进行了发展，并应用于地质、物探、化探、遥感信息的分析、提取和综合中，最后编制了综合矿产资源信息分析与预测系统。 结合高松矿田矿产预测的实际研究，主要取得了如下一些新的成果和认识： 提出了信息的本质是存在的体现，对信息量的综合表达发展了分层次的自相似加和方法。 对比研究了时间序列、空间序列、分形的分析体系，提出了在连续性基础上包容随机性的时空序列分析方法。 建立了高松矿田的化探原生晕模式，并对矿田内的断裂、地层、褶皱、花岗岩形态、花岗岩与褶皱协调程度等定性地质信息进行了分级和量化，对物探电测深信息进行了量化处理和综合解释。 构建并编制了综合矿产资源信息分析与预测系统。该系统可以将各种不同类型的信息按分层次自相似信息量加和的方法进行有机融合，由于使用了信息论的方法，能较好的解决地学中不同种类信息之间的叠合，更符合地学中的实际认识和规律。 应用该系统在高松矿田圈定了3级共18个预测区，其中1号一级预测区已经过验证，效果很好，达到了预测矿产资源的目的。更多还原

【Abstract】 This paper is one part of the science and technology cooperation item between Yunnan province and university/academy named The Research of Metallogenetic and Mineral Resource Predication in the Deep and Periphery of Gejiu Tin Deposit (2000YK-5), and is emphasized particularly on the mineral resource predication in Gaosong field. In the paper, geological, geochemical and geophysical information is analysed, picked up and synthetized mainly with the methods of information theory, time-space series and fractals. Then synthesis mineral resource information analysis and predication system is set up. With this system, 18 predication zones classed in three grades in Gaosong field are found. Fortunately, one of the predication zones is validated with well effect.Gejiu superlarge Sn-ploymetal deposit is the important tin producing area in our country and world. Up to present, its exploration history has been two thousand years, specially after the massive exploration after Liberation, the resource crisis is very severe. And it is necessary to explore other new resource base. Gaosong field is the only field in which work degree is low, and there is only a No. 10 group being mined. While some geological, geochemical, geopgysical data and a few drill data of Gaosong field having been accumulated after Liberation, and with the work of this time, it can be satisfied to predicate mineral resource in this field. So the research is concentrated in Gaosong field.Just because any single kind of mineral resource information can’t indicate the existence of mineral resource exactly while the synthesis of many kinds of mineral resource information can indicate the existence of mineral resource better, it can obtain better effect using synthesis mineral resource information to predicate the existence of mineral resource. Synthesis mineral resource information predication has been attempted in our country, and some obtained some effects. But because of the diversity, indirection and randomicity of mineral resource information, the classical data processing technique is difficulty to get marked effects. Thus the non-deterministic methods such as the information theory, time-space series and complexity are used to analyze, pick up and integrate the geological, geochemical, geopgysical and remote sensing information. At the same time, Synthesis Mineral Resource Information Analysis and Predication System (SMR1APS) has been written.With the example of mineral resource prediction research of Gaosong field, the following results are obtained:Information is the embodiment of existence, and synthesis information should be added with the grade self-similar method.The time-space series analysis method containing randomicity on the base of continuity is formed after the analysis systems of time series, space series and fractals are compared.Geochemical model of Gaosong field is set up. Qualitative geological information of Gaosong field such as fault, stratum, drape, shape of granite and the harmony between granite and drape is analyzed quantificationally. Electricity sound information is managed quantificationally and explained synthetically.Synthesis Mineral Resource Information Analysis and Predication System (SMRIAPS) is set up. In this system, many kinds of information are added with the grade self-similar method. Owing to the method of information theory, different kinds of geological information can be syncretized better, and accord to the practice geological understand and law.With the system, 17 predication zones classed in 3 grades is found, and No. 1 predication zone is validated with the better effect.更多还原
