2. Contribution to Civilization
• Mining is the Second Endeavours of
human civilization
• Agriculture and Mining Supply all the
Basic resources need in the modern
Civilization
3. History
Stone Age Prior to 4000 BCE
Bronze Age 4000 to 1500 BCE
Iron Age 1500 BCE to 1780 CE
Steel Age 1780 to 1945 CE
Nuclear Age 1945 CE to Present
• The history of Mining is parallels to
the History of civilization
• Many important cultural eras
associated with and identified by
various minerals or their derivatives-
4. Terminology
• Mine: An excavation made in the earth to extract minerals
• Mining: the activity, occupation and industry concerned
with the extraction of minerals.
• Minerals: a natural occurring inorganic element or
compound having an orderly internal structure and a
characteristic chemical composition crystal form and
physical properties.
• Rock: any naturally formed aggregate of one or more types
of mineral particles
• Ore: a mineral deposit that has sufficient utility and value to
be mined at a profit
• Gangue: the valueless mineral particles within an ore
deposit that must be discarded
• Waste: the material associated with an ore deposit that
must be mined to get at the ore and must then be
discarded. Gangue is a particular type of waste.
5. Terminology .....
• Metallic Ores: those ores of the ferrous metals (iron,
manganese, molybdenum and tungsten), the base metals
(copper, lead, zinc and tin), the precious metals (gold,
silver, the platinum group metals) and the radioactive
minerals (uranium, thorium and radium)
• Non-metallic minerals (also known as industrial minerals):
the nonfuel mineral ores that are not associated with the
production of metals. These include phosphate, potash,
halite, trona, sand, gravel, limestone, sulphur, and many
others.
• Fossil fuels (also known as mineral fuels): the organic
mineral substances that can be utilize as fuels, such as
coal, petroleum, natural gas, coal bed methane, gilsonite
and tar sands.

9. Stages in the Life of a Mine.....
Prospecting Exploration Development Exploitation Reclamation
Purpose: Search for ore
Procedure:
•Prospecting Methods
•Direct: physical geologic
•Indirect: geophysical, geochemical
•Locate favourable loci (map, literature, old mine)
•Air: aerial photography, airborne geophysics, satellite
•Surface: ground geophysics, geology
•Spot anomaly, analyze, evaluate
10. Stages in the Life of a Mine.....
Prospecting Exploration Development Exploitation Reclamation
Purpose: Defining extent and value of ore (examination
&Evaluation)
Procedure:
•Sample (drilling or excavation), assay, test
•Estimate tonnage and grade
•Valuate deposit, present value calculation, Feasibility
study, decision to abandon or develop
11. Stages in the Life of a Mine.....
Prospecting Exploration Development Exploitation Reclamation
Purpose: Opening up Ore deposit for production
Procedure:
•Acquire Mining right (Lease or purchase)
•File environmental impact assessment, technology
assessment, permits
•Construct access roads, transport system
•Locate surface plant, construction facilities
•Excavate deposit (Strip or Sink Shaft)
12. Stages in the Life of a Mine.....
Prospecting Exploration Development Exploitation Reclamation
Purpose: Large scale production of ore
Procedure:
•Factor in choice of method: geologic, geographic,
economic, environmental, societal safety
•Types of mining methods:
•Surface: Open pit/open cast, Placer etc.
•Underground: room and pillar, block caving etc.
•Monitor costs and economic payback: 3-10 years
13. Stages in the Life of a Mine.....
Prospecting Exploration Development Exploitation Reclamation
Purpose: Restoration of Site
Procedure:
•Removal of plant and buildings
•Reclamation of Waste and Tailings Dumps
• Monitoring of Discharges
16. Open Pit Mining
• Open Pit Mining is
the process of
mining any near-
surface deposit by
means of a surface
pit excavated using
one or more
horizontal benches.

17. Quarrying
• Surface quarries
resemble open pits,
but the benches
(faces) are lower and
generally vertical. The
high wall of a quarry
are often imposing
height and steepness,
sometimes attending
a vertical dimension.
Photo Custody: H L Hartman & J M Mutmansky, Introductory Mining Engineering (2nd Edition), John Wiley & Sons Inc
18. Open Cast (Strip) Mining
• Open Cast (Strip) Mining is a surface exploitation
method which resembles open pit mining but in this
method overburden is not transported to waste dumps
for disposal but cast directly into adjacent mined-out
panels.
Photo Custody: H L Hartman & J M Mutmansky, Introductory Mining Engineering (2nd Edition), John Wiley & Sons Inc
19. Auger Mining
• Auger mining is a
mining method that
recovers coal or other
minerals from under
the highwall when the
ultimate stripping
ratio has been
achieved in open cast
mining operations
