Objectives
 To develop a computer software that assist the mining
industry by providing a fast, accurate, and costeffective tool for ore reserve estimation and monitor the
changes in the spatial distributions sampling
parameters.
 Using the developed computer software to evaluate the
ore reserves of Maghara coal mine, Sinai, and generate
contour maps and three dimensional representation for
ore grades at the study area.
 Design a Mining Information System (MIS) for the
Egyptian Mines.

Conclusions
• A Software for ore reserve estimation is produced as an
end product of this graduation project. The Software has
introduced as a CD and has the following facilities:
 
Estimating the tonnage of ore reserve at acquired
area
provided that sufficient sampling boreholes are
available.
 
Calculating the area and average thickness or Assay
within any portion of the entire area.
 
Determine the lengths between any two sampling
points
using their X and Y coordinates.
 
Mapping the borehole locations in 2D and 3D
The Students designed a database to complete s MIS
