Survey and evaluation of coalfield geological exploration and coal resources based on remote sensing technology

摘要

With the development of computer science and information technology, computer data mining technology is updated, which makes the image mosaic technology that can detail data processing for remote sensing image. On this basis, this paper uses advanced computer image processing technology to carry on the combination of wavelet decomposition, combined with the GIS remote sensing technology, the coal exploration and investigation evaluation technique are carried out in-depth discussion. The paper establishes the mathematical model of GIS remote sensing image processing, and through the wavelet decomposition method, the function of image processing is given. In the third part, combined with the MATLAB data processing software, coal GIS satellite remote sensing image is carried out resource evaluation by the programming operation and the size distribution of coal rock is drawn, the coal content evaluation data table of remote sensing area is finally obtained, in which the content of No. 1 coal seam is highest reached 9860 tons, the horizontal extension of four coal seams is between 200–500m, and the longitudinally is extending between 50–100m.
