2. WHAT IS MINING
ENGINEERING ?
 The practice of applying engineering
principles and techniques for the
extraction of minerals for mine.
 WHAT IS MINE ?
 An excavation made in the earth to
extract minerals.

3. STAGES OF MINING
Mining
activity
involves
following
major stages
• Prospecting
• Exploration
• Development
• Exploitation
• Reclamation
AN OVERVIEW OF MINE LIFE 3

4. PROSPECTING (Looking for mineral
deposits)
DIRECT PROSPECTING
 Outcrop examination
 Geology of site
 Rock type (igneous, sedimentary, metamorphic)
 Structure (fault, joint, fracture, fold etc)
 Classification (clastic,acidic,mafic,foliated etc)

5. PROSPECTING (cont.)
INDIRECT PROSPECTING
 Geophysics
 Aerial photography
 Satellite mapping

6. EXPLORATION (Defining extent and value
of Ore body)
 Mineable reserves
 Drilling (core/non-core drilling)
 Laboratory tests
 Surveying (triangulation, traverse, theodolite
etc)
 Feasibility report
AN OVERVIEW OF MINE LIFE 6

7. DEVELOPMENT (Opening up ore deposit
for production)
 Acquire Mining rights (purchase/lease)
 Construct access road system
 Locate surface plant (In case of ore beneficiation)
 Storage (short/long term)
 Facilities
 Excavate deposit

8. EXPLOITATION (Large-scale production of
ore)
 Spatial Characteristics
 Geologic & hydrologic condition
 Geotechnical properties
 Economic consideration
 Technological factors
AN OVERVIEW OF MINE LIFE 8

9. MISCELLANEOUS
 Ore Beneficiation
 Finance & marketing
 Management
 Administration
 Mineral Economics etc
