15. DANGER DUE TO FIRE
& INNUNDATION
IN UNDERGROUND MINES

16. Definitions
• (10A) “fiery seam” means a seam in which a fire
or spontaneous heating exists in the workings
below ground or in open cast workings lying
within the precincts of a mine;
• (12) “gas” includes fume or vapour;
• (12D) “general body of air” means the general
atmosphere in a seam and includes the
atmosphere in the roof cavities, but does not
include general atmosphere in the sealed off
area or in any borehole drilled in coal or in the
adjacent “strata”;

17. Definitions
• (3) “Auxiliary fan” means a forcing fan or an
exhausting fan used belowground wholly or
mainly for ventilating one or more faces forming
part of a ventilating district;
• (4A)”Booster fan” means a mechanical ventilator
used belowground for boosting the whole
current of air passing along the intake or return
airway of a mine or ventilating district;

18. The Fire Triangle
Three things are needed for conditions to be right for a
fire to get started.
Now represents the “smoldering” mode of combustion.

19. Class A
Materials are:
Solids
• Wood
• Paper
• Plastic Rubber
• Coal
“A” stands for “ash”

20. How does a
solid burn?
Takes place as wood, coal, conveyor belts or any
carbon based products decomposes from the
action of the heat
Remember, it is the vapors that burn, not the solid.

21. How to extinguish a Class A fire
Limit material
Adding water burning
Class A fires Shovel away
only material
Add rock dust
to remaining
fuel
Pit a lid on it,
Use a fire
Usually oily extinguisher
rags or paper in
Usually Class
a waste
A, B & C fires
container

22. Class B
Materials are:
Liquids
• Gasoline, Oil, Diesel fuel
• Greases, Hydraulic fluid
• Gases; i.e.
Acetylene, Propane
Natural Gas
“B” stands for “boil”

23. Special care when using flammable and
combustible liquids
The “ flash point” is when at
the right temperature,
vapors are released that will ignite
Flammable Liquids Combustible Liquids
Flash point under 100oF Flash point over 100oF & under 164oF
•Gasoline(-42oF) •Diesel fuel(110oF)
•Toluene(73oF •Kerosene(102oF)
•Benzene(12oF) •Home heating fuel(120oF)
•Cleaning fluids •Hydraulic fluids

24. How to extinguish a Class B fire
Remove excess
Not liquid fuel or shut
recommended off bottled gas
Water can cause cylinders
the fire to spread
Put a lid on it Use a BC or ABC
fire extinguisher
No oxygen, no
fire

25. Class C
Materials are:
“Energized” Electrical
Equipment & Cables
Always treat “C” fires as though power is still on!
Once the power has been removed, you can probably treat it
like a Class A or B fire, but remember that cables &
equipment can hold electricity even after the power is off!
“C” stands for “current”

26. How to extinguish a Class C fire
Not Shut off the
recommended power
Water can May still have A
conduct electricity or B fire
remaining
May not work
because of the
Use a BC or ABC
high temperature
fire extinguisher
of the electric arc

27. Class D
materials include
Combustible Metals
• Magnesium
• Titanium
• Zirconium
• Sodium
• Potassium
• Lithium
• Calcium
• Zinc
D stands for “ding”

28. Class D materials are usually in alloy type
metals
They are usually started by a Class A-B-C fire, and will
burn at extremely high temperatures
Not Shovel away all
recommended- materials that can be
ignite by the high heat
The O2 and H2 in generated
the water will
accelerate the fire
Not recommended-
Attempt to isolate Unsure if ABC
the fire by covering extinguisher will put

dust Unsure of dangerous
by-product from the
reaction of the
chemicals

29. Class
K
This covers the new synthetic oils &
greases that are the market & the new
ones being developed
New synthetic oils &
greases for industry
Problem… ABC type fire extinguishers may not work on
these fires, a special Class K extinguisher may be needed!
Inquire about what new products that are available on mine
sites that would fall into this new category

30. Fire Extinguighers
Dry Chemical
•Ordinary Base “BC”
•Sodium Bicarbonate
•Potassium Bicarbonate
•Potassium Chloride
Do not use on “A” fires, will put out only
surface area, heated core may re-ignite
•Multipurpose “ABC”
•Monoammonium Phosphate
•Ammonium Phosphate
•Barium Sulfate

31. Classification of extinguishers
Type(s) of fire it
can put out
How much fire a
“lay person” can
put out
For example, a 5:A will put out five square foot surface area of Class A fire
A 20:BC will put out a twenty square foot surface area of Class B or C fire.
A properly trained person can extinguish 2 to 3 times the amount listed on
the rating.

32. When using a fire extinguisher,
remember the the phrase “P.A.S.S.”
•P. Pull the pin
•A. Aim low
•S. Squeeze the trigger/handle
•S. Sweep side to side
It is important that you should attend an actual
“hands on” fire extinguisher class to be
proficient in their use

44. Observations of New Kenda Court of Inquiry
• The court of inquiry appointed under section 24 of the
Mines Act, 1952 to enquire into causes and
circumstances attending the accident that occurred in
New Kenda Colliery of Eastern Coalfields Ltd.. on
25.1.94 causing loss of 55 lives due to fire, made the
following observations :
• 1. Workers shall be made acquainted with the existence
of escape routes/2nd outlets from work places/working
districts to the surface of the mine/mine outlets.
Maintenance of the escape routes should strictly be
adhered to and there must be markings/signs to indicate
such escape routes. Mock rehearsals shall be carried
out regularly to keep them aware of the escape routes.

45. Observations of New Kenda Court of Inquiry
• 2. There is an immediate need for development of
awareness amongst workers, supervisors and
management officials for identifying hazards due to fire
in underground coal mines. Intensive education and
training of the miners as well as supervisory staff shall
be taken up in this regard.
• 3. In belowground coalmines, efficient telephone
communication shall be provided and maintained from
the working districts/places to the surface.
• 4. In all working places in belowground and all other
places of fire risk such as coal stocks, spoil heaps
containing carbonaceous material and exposed coal
surfaces liable to heating, adequate quantity of water at
sufficient pressure for the purpose of efficient fire-fighting
along with other fire fighting equipments shall be
provided and kept maintained as required under
provisions of Reg. 120(1) (a) of CMR 1957.

46. Observations of New Kenda Court of
Inquiry
• 5. No person should be permitted to go belowground
without self-rescuer. It is mandatory as per Reg. 191D of
CMR 1957. It should be strictly complied with. Measures
should be taken for training and re-training of workmen
in proper use of self rescuers. Proper implementation of
safety measures in accordance with these observations
can bring about definite improvement in the safety
standards in the mines. Suitable steps may therefore be
taken early in this direction.

56. GASALITAND COURT OF ENQUIRY
• Inquiry—The Court of Inquiry appointed
under Section 24 of the Mines Act, 1952 to
enquire into causes and circumstances
attending the accident that occurred in
Gaslitand Colliery of M/s. Bharat Coking
Coal Limited on 27th September, 1995
causing loss of 64 lives due to inundation,
made the following recommendations :

57. GASALITAND COURT OF ENQUIRY
• (1) Before the onset of monsoon, mines situated
by the side of the river or other water sources
should be inspected by the Directorate-General
of Mines Safety along with the mine
management.
• (2) The feasibility of reclamation of opencast
workings including the disused ones, near rivers
and major sources of water, particularly those
having connections to belowground workings
either directly or through subsidence cracks and
fissures may be examined to prevent inundation
in such mines.

58. GASALITAND COURT OF ENQUIRY
• (3) Detailed precautionary measures against
danger of inundation should be laid down while
working beneath or in the vicinity of rivers and
major surface water bodies, particularly during
the rainy season. This may include framing and
implementing standing orders for safe
withdrawal of persons, provision of float alarm as
a means of warning in case of rise in water level
in the river in addition to river guards and an
effective and speedy communication system
which can function even independent of
electricity and work in adverse conditions.

59. GASALITAND COURT OF ENQUIRY
• (4) need for fore-warning the mines about
possible impending heavy rains, similar to
the warning of impending cyclone issued
in costal areas.
• (5) mines which have pits as the only
means of exit may require captive
generators in working conditions to run the
winders in case of emergency. In case of
steam boilers, the boilers to be under
proper shed with sufficient insulation
around the boilers and the pipelines.

60. GASALITAND COURT OF ENQUIRY
• (6) The need for an effective
communication system over and above
the signaling system between the surface
and belowground which shall remain in
operation even with failure of electricity
and also be rugged enough to remain
operative in adverse conditions has been
felt strongly. Suitable system may be
developed, if not already available and
used in belowground mines.

61. GASALITAND COURT OF ENQUIRY
• (7) In mines where the barriers have become
ineffective due to interconnections or otherwise,
the same may be restored early, even artificially,
by constructing suitable dams, explosion proof
stopping and other methods.
• (8) All disused pits, potholes and surface
subsidence existing in the vicinity of river or
surface source of water and where there is a
danger of inundation present, shall be sealed by
reinforced concrete seals or other suitable
effective means.

62. Additional Recommendations of Gaslitand
Court of Inquiry
• (1) Sanctity of mine boundary: A mine boundary
should be such as to contain hazards caused
due to mishap in a neighboring mine with the
help of suitable vertical barriers along the
boundary in all seams being worked. In cases
where such barriers do not exit, neighboring
mines will have to be isolated and protected with
construction of suitable protective measures
along the boundary in all seam workings keeping
in view of nature of the hazard. There should be
no horizontal transfer of property between two
mines.

63. Additional Recommendations of
Gaslitand Court of Inquiry
• (2) Embankment : Construction of embankment
is an engineering activity meant to provide
protective measures against hazard of
inundation from surface water. The current
practice of embankment construction is limited to
the geometric dimensions only. There are no
guidelines regarding the foundation design, the
material of construction, nature of slope facing
and the procedure of construction. There is an
urgent need for modification and framing
guidelines concerning the above parameters for
embankment construction.

64. Additional Recommendations of
Gaslitand Court of Inquiry
• (3) River channel: In the Jharia coalfield with a high
concentration of coal seams being worked in the
neighborhood and under the river channels, the later are
found perched at higher levels compared to the post-
mining depressed surface topography of the immediate
neighborhood. In case of breach of embankments
constructed to provide preventive measures against
inundation, the river course finds its way to the adjacent
depressed land thereby providing a large source of water
supply adding to the magnitude of the problem. Such
topographic changes in the surface profile need to be
prevented and/or remedied by suitable corrective action.

65. Additional Recommendations of
Gaslitand Court of Inquiry
• (4) Highest known flood level (H.F.L.): The
height of a protective embankment is related to
the HFL. The HFL on the other hand is related to
the amount of water flow in the river channel
during a particular year. This however
presupposes the cross section of the river
channel remaining undisturbed. In reality this
gets disturbed due to mining activity as well as
considerable amount of silting. Thus it would be
necessary to adjust the HFL according to the
changed river channel cross-section

66. Additional Recommendations of
Gaslitand Court of Inquiry
• (5) Abandoned pits : All pits proposed to be
abandoned are to be properly secured at the
collar level against hazards of inundation by
surface water. Managements are requested to
take suitable steps to implement the
recommendation of the court of inquiry in the
mines under their control.
