Generally, photographs are made in every half year,
using the scale from 1:5000 to 1:8000. The ortho-
photomaps are notable useful form of photogeological
elaboration of plane images for the necessity of mine
geological service. Orthophotomaps allow not only on
qualitative estimation of interpreted phenomena and
processes, but also on quantitative description.
As a rule, the possibility of uniform interpretation of
geological features exist with reference to main litho-
logical and structural elements. Engineering-geological
phenomena and processes are readable and all slope
deformation symptoms are easily recognizable.

Fig.9. Aerial viev along the slope of the dump, about
300 m in height. (each step is 30 m in height). Effects
of the reclamation activity are visible at the lower
part of the dump and also an erosion symptom is
easy to recoquize.
The stereoscopy observation allows for landslide
geometry definition, its morphological and structural
elements, and also for estimation of moving mass
volume. Aerial image enables moreover the examina-
tion of rising form in the more wide context of
geological slope structure, water conditions, etc.
The projection of images of elements serving to the
evaluation of land reclamation efficiency, realized
on stable slopes as well the strip mine as the
dumping ground is satisfied.
CONCLUSION
The remote sensing methods using for the geological
service of open-cast mines are notable useful and
desired. The results of realized experiments indicate,
that remote technic may be successfully applied to
solve so principal problems as actual mapping of
overlaid slopes specification and evaluation of
geological-deposit conditions, recognition and con-
