1. MINE HAZARDS(2162294)
MINES FIRES
SURAJ M BAMBHANIYA E.No.140153122001

2. 1.Presence of combustible material.
2.Presence of a source of ignition of sufficient
intensity of heat.
3.Presence of oxygen.
4.Contact of combustible material and source
of ignition for some time

3. Indian standards specifications classifies
fire as follows.
1] CLASS A FIRES
2] CLASS B FIRES
3] CLASS C FIRES
4] CLASS D FIRES
5] CLASS E FIRES

4. These fire involve
combustible material Eg.
Timber, Coal, Rubber,
Conveyor belt other
carbonaceous material

5. These fires involve
inflammable liquids e.g.
Lubrication oils, Diesel,
Petrol and other fuel oils
and greases etc.

6. These fires involve
gaseous fuels like LPG
gas, Butane etc.

7. These are metal fires
such as melting iron,
etc.

8. These fire involve live
electrical equipment such as
electric motors, Generators
cables, oil-filled
transformers, circuits
breaker, electronic
equipment

9. 1.Fire in store yards, engine houses .etc
(the causes of such fires are generally.)
A]. Electrical :Short circuiting of electrical
wiring, sparks from welding apparatus of
electric motors and equipment.
B].Embers of coal or other fires: Insufficient
care negligence cases spread of fire due to
these reasons.

10. C].Carelessly thrown cigarette, biristubs at
places containing kerosene oil, lubricating oil,
grease, Oil-soaked cotton waste, paper and
other combustible material.
D].Hot surfaces: Hot surfaces of electrical
motors, steam engines or internal combustion
engines in contact with combustible material:
hot wooden brake blocks of winders and other
engines.

11. 2.The possibility of fire in overburden
heaps near quarries is generally ignored.
Inferior coal And shale is very often
thrown into overburden dumps.in a large
number of cases , the shale bands so
dumped have some bright coal attached
to them.

12. 1.Steam rising from a coal stock is a warning
that heating is taking place. Presence of
moisture on surface of coal stock early in the
morning or late in the evening should not be
mistaken for “dew” these are indications of the
start of hearing . Observation of the
temperature is of course the most reliable way
to detect heating.
2.Seat of heating in a coal stock is nearly 0.6 to
1.5 m below the surface of stock.

13. 3.The coal stock in which heating has stated
should be drenched with water jets under
pressure. The quenched coal should be dug up
and spread in thin layers about 0.6m thick at
another place and allowed to cool down. such
cooled down coal should be the first to be
despatched.
4.Fire in the coal of bunkers(coal handing
plant) can be prevented by keeping a watch on
the hearing which may take place if the coal is
not despatched due to shortage of wagons.

14. 1.Check the workers, before they proceed
underground , for match box, cigarettes,biris,
cigarette lighters and other contrabands. This
is required under the coal mining regulations.
2.Do not allow burning of fires inside
mine(non-coal mine) and within 15m of an
incline/pit.

15. 3.Avoid welding of the headgear pulley or the
headgear frame unless proper precautions are
taken. Such welding in the case of coal mine
requires previous permission of the J.D.M.S
4.Avoid welding in underground repair shop
Without adequate precautions. if any repair
shop/workshop is to be provided underground
in coal mine prior approval of the J.D.M.S

16. 1.Check the workers , before they procced
underground ,for match box , cigarettes ,biris,
cigarette lighters and other contrabands, this is
required under the coal mining regulation
2.Do not allow burning of fires inside a
mine(non-coal mine) and within 15m of an
incline/pit
3.Avoid welding in underground repair shop
without adequate precaautions.
