3.3 Metamorphic rock area 
1. In middle to deep metamorphic rock area, it can 
commendably identify out image information of marble and 
quartz rock. According to the image marker strata, in 
epimetamorphism rocky area it can commendably carry out 
identification and mapping for stratum unit. 
2. It can better identify out old granite body of metamorphic 
rock region. 
3. According to structural feature of marker bed, it can analyses 
deformation process for metamorphic rock area and is also billy 
effective for identification of the deeper deformation band of 
alinement and reticulation. 
4. REMOTE SENSING SURVEYS FOR MINERAL 
RESOURCES 
Our country is rich in mineral resources and remote sensing 
technique is fully broad in application prospects. Remote 
sensing technique has already been comparatively mature in 
regional geological mapping and procured nice effects. There 
are also more discoveries in geologic structure and mineral 
study, with cycle largely shortened and expense economized at 
the same time. 
In survey aspect of geology mineral resources, remote sensing 
technique has developed from indirect detection to direct 
detection phase in our country, for instance, in Zhun Ge Er 
region of Xinjiang it directly detects out alteration zone of rock 
gold mine by using the subdividing infrared and multispectral 
scanning technology and achieves an important headway of 
remote sensing technique by which to directly search a gold 
mine. Our country also carries out the direct detection test of 
remote sensing of oil and natural gas resources by using short 
wave infrared imaging spectrum scanner in Xinjiang. Via 
information enhancement and extraction by using the remote 
sensing image data, it captures the hydrocarbon abnormity 
caused by microseepage leak on surface by oil gas accumulation, 
further achieves the purpose of direct detection. The project 
obtains confirmations in many production tests in Xinjiang 
Tarim Basin. Successful application of these technologies exerts 
an active action for expediting western development in our 
country. 
Aiming at coal industry taking manifold satellite remote sensing 
image as information source, it farthest extracts regarding rock 
(sedimentary rock, magmatic rock and metamorphic rock), 
strata (especially coal bearing strata), structure, coal geology 
abnormity and other information within survey areas, combined 
with predecessor's data, analyze geologic structure characteristic 
and coal geology basic feature of region of interest, unfolds the 
demonstration working of field investigation, understands the 
upgrowth characteristic and deposit state of coal bearing strata, 
studies coal accumulation regularity and delineates coal bearing 
prospect area. 
Taking visual interpretation as predominating and computer 
information extraction image as supplement, image explanation 
mainly explains regional control basin, coal controlling fault, 
stratal distribution, lithology, lithofacies and thickness changes 
orderliness, dislocation, plicated property, scale and upgrowth 
characteristic, finally establishes interpretation symbols of 
remote sensing of strata and structure and frames out the 
demonstration plan of field investigation. To extrude the 
characteristic of coal-bearing strata and non-coal-bearing strata, 
it enriches image information of dislocation, fold and other 
structures, enhances explanation effect, feasibility and 
foreseeability of survey working. It can also carry out digital 
enhancement processing for image by manifold methods. 
Remote sensing geology explanation and field investigation 
demonstration can ascertain the epoch, distribution range, 
depositional feature of coalbearing strata and change of 
coalbearing features. By analyzing space distributive orderliness, 
on the basis of survey comparison for correlative layers, it can 
delineates various coalbearing strata in survey area. 
Via information extraction of geognosy of remote sensing 
image, it can explain and verify main fault structure within area. 
According to every geology block characteristic and boundary 
fault property, starting from coal series gather and deposit 
background, structural unit can be partitioned to analyze control 
action of rupture and all levels of structural unit for coal series. 
Via analyses and research for age-old geography of gather coal 
acting, ancestral structure evolution, gather coal action, gather 
coal basin genesis of various periods, it can ascertain type of 
gathering coal basin in area. 
Tectonic framework of remote sensing geology of work area is 
established to analyze the control action of coal structure for 
coal basin and coal series, to study coal basin genesis, to 
ascertain distribution range of coal basin and coalbearing strata, 
to understand upgrowth and deposit characteristic of 
coalbearing strata, to study ancestral structure, age-old 
geography and depositional environment of coalforming period, 
to analyze reconstruction action of anaphase structure for coal 
basin, coal seam and coal quality, to summarize coal 
accumulation regularity, under precondition of mastering coal 
accumulation regularity fully and to delineate prospect area of 
containing coal. 
Applying remote sensing technique to carry out coal resource 
survey possesses accuracy, high efficiency, economy and a 
good many of other predominance, especially on occasions in 
which work area is bad in natural conditions, inconvenient in 
traffic, coal geology study is low in degree, it can exert fully 
remote sensing technique’s predominance and procure new 
outcomes. 
5. MINE FIELD GEOLOGIC HAZARD MONITORING 
AND GOVERNING 
Coal district geologic hazard is mainly surface collapse, fracture, 
mine water invasion caused by underground mining and coast 
and fracture generated by open pit mining. In underground 
production area surface collapse and fracture ordinarily exist in 
coalfield district, especially in exploitation of major scale coal 
industry base, it is more striking. The surface of working 
section is in the instability in long term, harmful to tilth, bourg, 
road facility and mine safe production in mining section, 
already becoming an important factor to restrict area economic 
development. Along with increase of mining depth and 
complexity of exploitation conditions, especially exploitation in 
minefield of complex hydrogeologic condition, mine water 
invasion will also be increasingly striking. In addition, coal 
gangues pile up in various coal districts and occupy more than 
9000 mou, in which to occupy farm area of about 3000 mou. 
Main harms of coal gangue are spontaneous combustion, dust 
nuisance and explosion, pollution of minefield environment and 
harm of human health.
