【摘要】 随着国民经常的快速发展,对矿物原料的需求日益增大,同时因近地表矿产资源与已开采矿山资源的日趋枯竭,造成找矿难度的加大。为满足经济发展的需求,新理论、新技术被应用于地质矿产勘查中,形成丰富了成矿理论,并获得了较好的找矿成果。如何运用遥感手段更好的指引找矿,快速、正确圈定靶区,为矿区深部及外围找矿提供科学依据。本论文利用了ETM遥感图像数据以科研项目《云南省昭通炎山铅锌矿矿区遥感信息融合与成矿预测》为支撑,在计算机辅助软件地理信息系统和ERDAS系统平台上,运用遥感技术,对矿区周边及其深部进行新资源的探察,能快速对某一区域进行靶区圈定,大大缩短了实地勘探的周期,并能节省大量的人力和物力资源。作业在收集前人对研究区所做地质资料的基础上,通过实地勘察,并对遥感解译进行实地勘察。通过对地质与遥感解译信息综合分析,建立综合信息找矿模型,获得以下认识和成果：1.实现了空间数据与属性数据的一体化管理,集地质和遥感为一体,快速提取和筛选找矿信息；2.在计算机辅助软件ERDAS平台上对ETM遥感图象数据进行处理,提取矿化信息,并对研究区的线形构造线和环形进行了分析与提取,并采用MORPAS软件系统对线性构造进行等密度、平均方位、条数、优益度、中心对称度定量化处理；3.将遥感影象图解释为环形构造和线形构造,并从中提取矿化信息,用GIS作为辅助工具,从数据层次上实现RS和GIS的集成；4.通过对遥感解译图象的实地勘察与验证,综合地质和遥感信息,在研究区进圈定了5个靶区,并对其进行了初期规划,通过工程验证,取得了良好的效果。
【Abstract】 With the rapid development of the national regular on the demand for mineral raw materials are growing at the same time because of the near-surface exploitation of mineral resources and mining has become increasingly depleted resources, resulting in the increased difficulty of prospecting. In order to meet the needs of economic development, new theories, new technologies are used in mineral exploration geology, the formation of enriched mineralization theory, and obtained better results prospecting. How to use a means of better guidelines for remote sensing exploration, rapid, and the correct delineation of target for mining exploration in deep and peripheral to provide a scientific basis.In this paper, using the ETM remote sensing image data in order to research Yan Shan in Zhaotong of Yunnan lead-zinc mining areas of remote sensing information fusion and metallogenic prognosis" for support in computer-aided software ERDAS geographic information systems and system platforms, the use of remote sensing technology, surrounding the mining area and its deep resources for new detectors that can quickly target a particular area delineation, greatly reducing the field of exploration of the cycle, and can save a lot of human and material resources.In the collection made by our predecessors of the study area based on geological data, through field investigation, remote sensing interpretation and field investigation. Through the interpretation of geological and remote sensing information analysis, the establishment of an integrated model of information exploration, knowledge and the results of the following:1. accomplish the geological and remote sensing information quickly;2. Process the remote sensing image(ETM) by utilizing the methods for digital image processing, extract mineralization information, interpret the line and ring structure. Achieve a great deal of fixed-quantity information by means of the software of MORPAS, such as equivalent density, average direction, item quantity, outstanding degrees, symmetry degree of centre. Summarize the prospecting model of remote sensing;3. Remote sensing images will be interpreted as a circular graph structure and linear structure, mineralization and extracting information, using GIS as a tool to achieve from the data-level integration of RS and GIS;4. Interpretation of remote sensing images through the site investigation and verification, integrated geological and remote sensing information in the study area has been delineated into five target, and its early stage of planning, engineering verification, achieved good results.
