As a kind of specific bad geology phenomena, No matter 
whether landslides, collapse, mudflow and other disasters or 
disaster colony formed by them, the shape, hue, image texture 
structure and so on they assume on remote sensing image have 
definite difference with circumjacent background. Thus it is 
directly identified and delineated from remote sensing image for 
scale, morphological characteristics and gestation feature of 
collapse, slide, mud and other geologic hazards, by which it can 
carry out systemic and comprehensive survey for generant 
geologic hazard points and hidden danger points of geologic 
hazard in target area via remote sensing explanation of geology 
disasters to ascertain their distribution, scale, formation cause, 
upgrowth feature, development trend, harmfulness and 
influencing factor, on the basis of which to carry out geologic 
hazard zoning, to partition easy occurring geologic hazard, to 
appraise easy occurring degree and to furnish base data for 
preventing the geologic hazard hidden danger and establishing 
the geologic hazard monitoring network. 
On the basis of using high resolution satellite image or aero 
photographic image to carry out remote sensing explanation, 
geologic hazard distribution graph can be compiled via 
explanation and survey for coast, dilapidation, mudflow and so 
on. It can express a variety of geologic hazard position, 
boundary, element and other time and space features and plane 
scale in detail and become one of important base data and basic 
gist of planning and design even geologic hazard evaluation, in 
addition, it can also carry out disaster genetic analysis and trend 
anticipation from macroscopy. 
Governing for geologic hazard shall first master extent of 
damage and development trend of geologic hazard, which 
includes casualty of personnel and livestock casualty, loss of 
village, mine, highway, bridge, hydraulic architecture and other 
property as well as demolition of soil, forest, water area and 
other natural resources. Using remote sensing technique to carry 
out geologic hazard survey, except that casualty of personnel 
and livestock is difficult to be statistic, can carry out real-time 
or quasi real time survey and evaluation for demolition situation 
of engineering facilities and natural resources and furnish the 
exact gist for disaster salvage. 
Remote sensing technique is one rising hi-tech means. Not only 
it is necessary, but also feasible that using remote sensing 
technique unfolds the geologic hazard survey. Remote sensing 
technique can be transpierced to overall process of survey, 
monitoring, pre-warning and evaluation of geologic hazard. 
Along with gradual perfection of remote sensing technique 
theory and gradual elevation of spatial resolution spatial 
resolution, time resolution and spectrogram resolution of remote 
sensing image, remote sensing technique will certainly become 
one of indispensable means of macro-survey of geologic hazard 
and environment of pregnant disaster as well as evaluation of 
disaster body dynamic monitoring and the situation of disaster 
loss. 
6. GEOLOGIC EVALUATION OF MINE FIELD 
ENGINEERING 
Surrounding mine field infrastructure construction, it carries out 
engineering geologic investigation and appraisal of remote 
sensing of road, the site of factory and other engineering types 
and fully exert intuitionistic, fast, exact, high efficient 
predominance of remote sensing technique. On the basis of 
analyzing the existing area geology and bad geology, taking 
satellite image as basic information source, It unfolds the 
engineering geology remote sensing explanation, entirely 
extracts relative topography and relief, stratum lighology, 
geologic structure, hydrogeologic condition, engineering 
geologic condition, bad geology, vegetation and other 
information and carries out field investigation validation. Via 
aggregate analysis study, it initially ascertains engineering 
geology actuality, bad geology phenomenological type, 
distribution state, upgrowth feature, development trend and 
vegetational type, coverage and height, appraises engineering 
geologic condition and stability zone by zone to carry out sub 
area by engineering geology complexity for entire project area 
and presents the corresponding updated scheme and next step 
survey working proposal. 
6.1 Engineering geology remote sensing analyses 
1. Geomorphy type remote sensing analyses 
According to relief genetic type and morphological 
characteristics, different relief genetic type possesses different 
image texture, drainage type and other image features, by 
remote sensing explanation, it can carry out a partition for zonal 
relief. 
2. Rock soil mass type remote sensing analyses 
On the basis of full explanation of stratum lithology, based on 
rock type, structure fabrication, formation rule, physical 
mechanical property and so on, it can carry out engineering 
geology rock formation partition for rock soil mass in area. 
6.2 Geologic structure remote sensing analyses 
By explanation of fault structure property, scale, space 
distribution feature, it ascertains relative time sequence and 
explains the active structure and focuses to analyze the possible 
generant impact for engineering. 
6.3 Hydrogeologie condition analyses 
Deposit and distribution of underground water are mainly 
subjected to be controlled by geologic structure, relief, lithology, 
climate and ancient landform conditions. According to 
explanation for water-bearing rock within area, combined with 
deposit condition and waterpower feature, it can carry out 
appraisal for underground water type and water abundance. 
6.4 geological hazard remote sensing analyses and easy 
occurring degree forecast 
With essential information source of satellite image, via remote 
sensing explanation, field investigation validation and available 
information analyses, it can ascertain coast, dilapidation, 
mudflow, instability incline and other bad geology phenomena. 
On the basis of explanation of bad geology points in detail, 
based on principle of whether to have effect for engineering; 
principle of mean upgrowth density of bad geology phenomena; 
principle of topographic relief, engineering geology rock 
formation, geologic structure and inducing factor similarity; 
principle of regional engineering geology condition integrality, 
it adopt a fuzzy mathematics syntheses judge method to carry 
out analyses of forecast and partition for easy occurring degree 
of bad geology.
