2.  Prospecting
it is the first stage in the search of ore.
In this we study the literature and maps of
an area.
There are two methods of prospecting.
1. Direct method
2. Indirect method

3.  Direct
method
 It is limited to deposits on surface or near
surface.
 it consists of visual examination of either
outcrop or loose fragments that have
weathered away from the outcrop
 The samples are collected from the
potential site for microscopic study in
laboratory.

5.  Indirect
method
 These can be used for deeper deposits.
 They include seismic ,radiometric ,
magnetic and many other methods.

pics for seismic and these surveys

7.  Exploration
 2nd stage of mining
 Core
samples are obtained by diamond
drills.
 Different laboratory analyses are carried
out to evaluate the grade and tonnage of
deposit.

12.  Final
conclusion is drawn regarding worth
of the deposit.it is called reserve
estimation.
 At the end of this stage feasibility study is
carried out which helps to decide, whether
to abandon or develop the deposit.

13.  Development
 It
is work of opening a mineral deposit for
exploitation.
 With it proper mining begins
 In this stage mining rights are acquired
 Access roads to site are constructed
 Power source is acquired

14.  Ore
handling and treatment plants
constructed .
 Then access to deposit may be gained by
1. Stripping overburden (surface mining)
2. By excavating openings from surface to
more deeply burried
deposits(underground mining).

18.  Exploitation
 It
is actual recovery of mineral
 While development work continues
through out life of mine, in exploitation
stage main emphasis is on production.
 In this stage mining method is also
selected.

19.  Mining
method selection
 The selection of mining method depend upon
1. Economics (comparing costs)
2. technology available
3. Size , shape and depth of ore
4. Ground water,strength of ore and host rock
5. Environmental factors as subsidence on
surface,ventilation,work force etc.

21.  Surface
methods
 Two main types
1. Mechanical excavation
2. aqueous excavation

22. Mechanical excavation methods
1. Open pit mining (thick deposit)
2. Quarrying (thin deposit)
3. Opencast mining,etc

29.  Underground
mining methods
 Three classes
1. Unsupported methods(room and pillar)
2. Supported methods(cut and fill, )
3. Caving(, block caving)
