1. Introduction
The use of computer facilities has become
widely increased in different areas.
Mining engineering in general and ore
reserve estimation in particular are
among these applications.
2. Objectives
To design a suitable database for the Egyptian
mines and quarries.
Not only:
But also:
Moreover:
names and locations of the mines,
current mining operations, machines,
economics and environmental issues,
geological maps, and
A simple computer software for ore reserve
estimation and calculations of the ore
average thickness and grade.
3. Problem Definition
Problem 1
Lack of information required for research
work and investors.
Problem 2
Conventional methods are not accurate, time
consuming.
Problem 3
Advanced techniques (Geostatistics) are
costy, and still complicated.
4. O.R.E Software
For each triangle
1. Average thickness =
h1  h2  h3
3
2. Average assay =
A1h1  A2 h2  A3h3
h
3. Area of triangle =
p p  L1 p  L2 p  L3
For the total area
1. Average thickness =
A1 h1  A2 h2  A3 h3  ..........  An hn
A1  A2  A3  ..........  An
2. Average assay =
Volume  Assay
Volume
3. Tonnage =
 Area  Average thickness

Charts
Fast, accurate, and cost-effective tool
All internal calculations use
16 digits after the decimal point
Just enter your data , all results and
Data analysis are ready for you.
Monitor the changes in the special distributions
of sampling parameters
You can change, modify, add or remove any point
and see the effects instantaneously
More advantages
You can add assumed
points anywhere and
estimate the ore and
other metals at these
assumed points
It is so easy, just right click
On any place and choose
“Add assume”
All detailed information
And estimation about
An assumed point
You can measure
the length between
any two points
It is so easy , just press
The mouse and move

Validation
In order to examine the reliability of the
developed Software, the result of ore
reserve estimation of the (MCS) * is
compared with the last report about the
same area and provided by the Ministry
of Industry and Mining Projects Egypt
(1996).
• Proved ore reserves of the (MCS) = 27
million tons (report).
• Calculated ore reserves using O.R.E
software =26.62 million tons.
5. Mining Information
System (MIS)
A database system that involves
information and data about mining sites
in a way that the data can be retrieved,
updated and manipulated easily to
produce useful information.

6. Conclusions
An outline of designing a database for the
Egyptian Mines has been introduced.
A new Software for ore reserve estimation has
developed and used with the following
facilities:
• Estimating the tonnage of ore reserve for the
considered area; provided that sufficient
sampling data are available.
• Calculating the area, average thickness or
assay within any portion of the entire area.
A list of the most important information
that required for the aimed database
have been addressed.
A questionnaire is being prepared and will
be sent to the Egyptian authorities and
mining companies to cooperate and
provide the required information so that
a complete database can be created.
Thanks for your attention
