| The Yunnan Lancang Laochang silver plumbum ore is the large-scale multi-metallic ore deposit with more than 500 years mining histories, but the mine reserve resources is unclear, the resources question has become the serious restriction mine enterprise to develop, even becomes the basic question to threatens the enterprise survival. With mineral resource unceasing mining and consumption, the unknown minerals have lie concealed the nature, and the geological work degree low region often is following the difficult natural condition. Under current technical background, Remote sensing data precision large-scale enhancement, has better macroscopic and microscopic, thus enable function of the remote sensing geology the resources investigation to obtain the enhancement. With the remote sensing science and technology the efficiency high, the speed quick, the precision good, the cost low status merit, and the remote sensing image performance geologic structure is clear, according to the minerals and the geologic structure relations, geologist often may discovers the mine point or carries on the mine forecast from the remote sensing material. Therefore, Exploring remote sensing geology information extraction as the center of prospecting technology plan is a current geological work important research direction.This article connects the Yunnan Province provincial acadmy provincial school cooperation project "Three-dimensional Localization Forecast and increase mine resources Research of the Yunnan Lancang Laochang silver plumbum multi-metallic ore ". Explores remote sensing geology information extraction as the center of prospecting technology plan, synthesizes utilization remote sensing digital image processing (including image enhancement and multi-source data fusion) and the GIS space analysis method, unifies the outdoors geology investigation and study, obtains following several aspects result:1st, the lancang laochang ore remote sensing interpretation symbol were Established.2nd, the research area mineral alterations information were identifiedby using the wave band ratio and the colored synthesis of TM Data.3rd,the research area line-circular structure information were interpreted and the relationship between the line-circular structure characteristic and the mine were analyzed.4th, the multi-source information of the research area were fused, processed, and the mineral prospecting area were selected by using multi-source remote sensing data fusion technology.5th, Lancang laochang DEM were built, explored mining area three-dimensional visualization based on the remote sensing phantom support and the geological multi-source information three-dimensional visualization technology. This will serve for prospecting ore position and developing geology work. |
