This was given the possibility of the geological features detection in the open-pit mine, reclamation activity registration 
> OF on the dump body and inventory of mining operation. A quantitative comparison of all used merging methods is also 
carried out for the set of colour composite using approach proposed by Wald et al. (1997) and Mularz (1996). 
  
2 STUDY AREA 
The Lignite Open-Cast Mine “Belchatow” has been 
chosen as a study area. It is located in the central part of 
Poland, southwest from Warsaw in distance 150 km 
nine approximately. The mining area consists of open-pit mine, 
a dump body and electric power plant (Figure 1.). A size 
of the open-pit mine was about 2.5 km wide by 6.0 km 
long and about 250 m in deep.
