ABSTRACT: 
Remote sensing technology possesses high speed, real-time and other features of information acquisition and processing and can 
extensively be used in renewal of topographic maps, mapping of high precision remote sensing geology, mineral resources remote 
sensing survey, monitoring and governing of coal mine geologic calamity, coal mine engineering geologic evaluation, mine 
ecological environment monitoring and governing, mine field land use/cover change monitoring, mine field planning and other 
domains. By synthetically using multi source remote sensing technology, We can realize informational fast collection, processing and 
furnish the strong basic information and decision support for leader decision. It will surely bring the revolutionary advancement for 
coal industry to apply multi-source remote sensing technology to coal resource exploration and coal industry digitalization 
construction. 
1. INTRODUCTIONS 
Our earth is one planet with limited resource. Along with 
increase of earth population as well as humanity continuous 
pursuance for material civilization, pressure confronted by 
earth's resource and environment is continually intensified, 
resource is in exhaustion and environment is in deterioration. 
All these require people to know and understand our earth once 
again. How much resource can we still utilize to the end and 
how are on earth our surrounding environments ? Remote 
sensing technique is a kind of strong means of solving these 
problems. Remote sensing technique is a technology that carries 
out detection and discrimination for objective by perceiving the 
electromagnetic wave, visible light and infrared of target 
reflection or self-emitted radiation at long range. In the recent 
20 years, the observation development and application of global 
space to ground has shown that aerospace remote sensing 
technology is a high-tech with comprehensive application and 
an importance scale of measuring science and technology 
development level of a country. Now no matter whether west 
developed countries or developing countries in Asia Pacific 
region attach full importance to develop the technology and 
hope that aerospace remote sensing technology will be able to 
furnish powerful impulse and reliable strategically decision gist 
for state economy constructional leap. Current remote sensing is 
no longer a simplex information acquisition and analytic 
technique means. Combined with geographic information 
system, global positioning system, a variety of surface 
observation technology, information analysis technology and so 
on, it is forming one brand-new earth information science. It is 
changing our conception, enhancing our ability and playing an 
active impulse role to promote new decision, management, and 
development model of humanity. The applied analysis of 
remote sensing information has been changed from single 
remote sensing data into mix and analyses of multi-time phase, 
multi-data source, from static analysis into dynamic monitoring, 
from qualitative survey for resource and environment into the 
computer aided ration autodraft, from surface description for a 
variety of phenomenon into software analysis and measure 
exploration. 
Resolution of current remote sensing satellite image, in more 
than 30 years of satellite remote sensing appearance, has been 
enhanced rapidly, including spatial resolution, spectral 
resolution and time resolution. Spatial resolution refers to the 
least target dimension on ground seen from image, which can be 
expressed by the pixel size on ground. It has already been 
upgraded from 80 meters at the beginning of remote sensing to 
30 meters, 10 meters, 5.8 meters, or even 1 meter, 0.61 meter, 
even 10 centimeters reachable in military purpose. Spectral 
resolution refers to imaging wave band scope. The more finely 
it is divided, the more the wave band, the higher the spectral 
resolution. Current technology can reach 5—6nm magnitude, 
with wave bands of more than 400. Subdividing spectra can 
enhance the ability for partitioning and identifying a target 
property and composition automatically time resolution refers to 
duration of re-access cycle. Presently earth-oriented satellite is 
the re-access cycle of 15 - 25 days in general. By launching the 
satellite constellation with reasonable distribution it can realize 
that earth is observed one time per 3—5 days. Thus it can be 
seen that remote sensing technique possesses high speed, real 
time and other features of information acquisition and 
processing, at the same time it can be provided with high 
precision and quantification of application, etc. By synthetically 
using multi-source remote sensing technique it can realize 
informational fast collection and processing and furnish the 
strong basic information and decision support for leader 
decision. It will surely bring revolutionary advancement for coal 
industry to apply multi-source remote sensing technique to coal 
resource exploration and coal industry digitalization 
construction.
