SOME CRITICAL ISSUES OF THE INDIAN COAL MINING INDUSTRY
PREPARED BY :KALYANI JHA
INDIAN MINERAL RESOURCES India has ample amount of mineral resources.
Indian has gained high momentum of production
on various mineral resources.
Among such mineral coal stand on the first
position.
FIRST CRITICAL ISSUESPONTANEOUS HEATING
SPONTANEOUS HEATING
Spontaneous heating is the process of heating of
coal after some period.
The period after which spontaneous heating
takes place is called incubation period.
CONT… Heating of the coal takes place after exposure of coal
to the atmosphere.
This heating of coal takes face of dangerous fire.
The problem of fire is an old as an history of mine.
Best example: JHARIA COAL FIELD.
CAUSES OF MINE FIRE
In O/C mine
Spontaneous heating
In U/G mine
Sluggish ventilation
Improper roof support in underground mine
Incomplete extraction
SECOND CRITICAL ISSUEVENTILATION PROBLEM
In underground mine ventilation is the big
problem.
The sluggish ventilation causes various problem
to the workers at working phase
Various gases comes out during extraction
process. Such as CO, CH4 etc
CONT…
The main gas which is dangerous for workers is
methane.
The high quantity of methane in mine cause fire damp
explosion .
Insufficient ventilation causes coal dust explosion.
VARIOUS OTHER ISSUES
Since the workers of the mine are unskilled and
not properly trained.
This unskilleness and improper training may
cause various accidents in the mine and various
economical loss.
PREVENTION TO BE TAKEN Proper care should be taken so that spontaneous
heating should not take place, such as:
1) Coal piece should be covered with plastic cloth.
2) If heating of coal is seen then water should be
sprinkled immediately on coal.
3) New mining method for complete extraction of
coal.
PREVENTION FOR VENTILATION PROBLEM
Proper ventilation arrangement should be made.
Ventilation arrangement should be made such
that fresh air should reach at working face.
Ventilation should be such that cool atmosphere
must be maintained under mine.
OTHER PREVENTION Worker of the mine should be well trained before
giving entry in the mine.
They should be given various information about
the machine which they are going to operate.
