6.5 Engineering geology complexity partition
On the basis of region stability, it can be measured mainly from
topographical relief, stratum lighology, fault structure, rock soil
mass property, bad geology phenomena, hydrogeologic
condition, recent tectonics movement, Earthquake and other
aspects. It also considers the productive state of rock and human
activities of destructing geology environment and other factors,
adopts qualitative evaluation method and carries out partition
for complexity degree of engineering geologic condition of the
project area.
6.6 Engineering geologic evaluation and scheme selection
On the basis of appraisal partition and engineering geology
division for the relief, structure, hydrological geology, bad
geology, engineering geologic condition and others, it carries
out analysis appraisal for engineering geology characteristic and
main engineering geological problems of the project area and
carries out selection for the drafted scheme.
7. MINE ECOLOGICAL ENVIRONMENT
MONITORING AND GOVERNING
Ecological environment has already become one of focal points
of government and public attention, especially a frail ecology
cold and dry area like our country’s west, it is fully important to
carry out monitoring for ecology environment. Mine ecological
environment problems mainly include open exploitation delay,
goaf, ore tailing, wastewater, groundwater overdraft and others.
Because it is remarkably clear and striking that various ecology
elements are represented on remote sensing map, furthermore it
is very easy to distinguish out their size, shape, area and other
elements, it can use remote sensing image to carry out
identification and plotting for main ecology factors. All mine
ecological environment problems have the direct or oblique
reflection on remote sensing image, thus it can also find up their
distribution scope, area and others by remote sensing
explanation combined with field investigation mode.
On the basis of remote sensing investigation of regional
ecological environment and mine field ecological environment
problem, the suggestion for ecological environment governing
is presented. The governing for mine ecological environment
mainly includes re-cultivation, re-green, tailings disposal and
use, waste water treatment and use, groundwater overdraft
monitoring and control, development and use of mine disuse
terra and disuse engineering facilities.
Using remote sensing multi-time phase feature can not only
make out a judge for ecology actuality, but also monitor its
change trend and governing result.
8. MINE FIELD LAND USE/LAND COVER CHANGE
MONITORING
Using multi-source remote sensing data can carry out a
geometry correction, calibration, mix together, mosaic,
enhancing processing to enhance spectral recognition ability for
ground objects; Then, it carries out direct calculation of point-
to-point for mine field different time-phase remote sensing
image and adopts computer and manual work methods to find
change information for land utilization type. Via fieldwork
verification, it can ascertain mutative position, scope, type and
area to realize fast monitoring for mine field land use and
overcast change and furnish a gist for mine field planning and
development.
9. MINE FIELD PLANNING
Via remote sensing geology mapping and mineral resources
survey appraisal, it realizes exploration for mine field coal
resource and analysis of existing circumstance of development
and use. Via ecological environment survey it realizes analysis
of existing circumstance for mine ecological environment. By
monitoring mine field land use / overcast change, it realizes
analysis of existing circumstance for mine field land use;
Combined with supply and demand situation analyses and
forecast of mineral resources, it ascertains the program
objective mission. By engineering geologic investigation of
remote sensing, it ascertains the planning scheme; thereby
realizes integral planning for entire mine.
10. EPILOGUES
Satellite remote sensing can cover every comer of earth. For
any country and region it does not exist any blank area of
information acquisition caused by nature or social factors,
satellite remote sensing document can timely furnish spatial
information of identical time phase, identical wave band,
identical scale, identical precision for spacious regions and
manifold remote sensing information source of heterogeneous
and different scale, such as multispectral ETM + , SPOT,
CBERS, IKONOS, Quickbird and others, high spectral MODIS,
Hyperion, aviation imaging spectrograph OMIS and others,
synthetic aperture radar image such as RADARSAT, ERS,
JERS and others. It furnishes numerous selection for coal
resources exploration and relevant information acquisition and
possesses extensive application prospects.
