  1. 1. Muhammad Anus 14MN36 Department of Mining Engineering MEHRAN UET, JAMSHORO
  2. 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. AN OVERVIEW OF MINE LIFE 2
  3. 3. STAGES OF MINING Mining activity involves following major stages • Prospecting • Exploration • Development • Exploitation • Reclamation AN OVERVIEW OF MINE LIFE 3
  4. 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) AN OVERVIEW OF MINE LIFE 4
  5. 5. PROSPECTING (cont.) INDIRECT PROSPECTING  Geophysics  Aerial photography  Satellite mapping AN OVERVIEW OF MINE LIFE 5
  6. 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. 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 AN OVERVIEW OF MINE LIFE 7
  8. 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. 9. MISCELLANEOUS  Ore Beneficiation  Finance & marketing  Management  Administration  Mineral Economics etc AN OVERVIEW OF MINE LIFE 9
