NOT EXPLOSIVE MIXTURES

SMOKE AT INTAKE AIR SHAFT AT THE TIME OF SEALING

Dealing/ Monitoring of Fire

Surface Bore holes(18 Nos) plugging done. Crack Filling over goaved out panels was done. Mine air samples not obtained due to negative

pressures after closing of mine entries and with

establishment of pressure balance chambers

(sliding doors with auxiliary fans) at Manway, Main

Incline on 18/07/08 and Fan shaft on 21/07/08 and

Air samples were collected.

Dealing/ Monitoring of Fire

Surface Bore holes(3 nos) were drilled to 1A Seam and 1Seam for inertisation and monitoring of gas samples.

372 ( each 7000 lit) nos. of CO2 cylinders were flushed through to surface bore holes and Air shafts.

10 tonnes of liquid CO2 was flushed through return air shaft.

Air samples were collected from surface bore holes, mine entries and inter seam bore holes from RK-7.

Bore holes temperature was monitored.Regular inspection and monitoring was done.All the works were carried out under Rescue cover.

Interpretation of Mine Air samples

Interpretation of mine air samples from 14.07.08 to 05.08.08 revealed the fire has died down. Details are as below.

Oxygen was dropped to 0.961% from 17%. Carbon monoxide was dropped to 0 from 4.440%. Methane dropped to 0.725% from 1.360%. Hydrogen was dropped to 0% from 3.180%. Effective combustibles were dropped to 0.72 from 6.710. CO/O2 ratio was dropped to 0 from 64. Effective inert was increased to 99 from 11. Carbon dioxide was increased to 8 % from 2.3 %. R value was increased to 1 from 0.1 resulted in reduction of

explosive mixture area.

IMPOSSIBLE MIXTURES


RE-OPENING OF MINE

Re-opening of mine is under taken from 06/08/08 and still continuing. The sequences are as below

Initial openings were made at main incline, man way and intake air shaft and ventilation circuit was established with 20HP auxiliary fan and explored the workings up to 4L and air intake air shaft.

Stoppings were built at entries to 1 Seam at main incline, man way and 5L tunnel to cut off air supply to 1 Seam workings.

Opening was made at return air shaft and ventilation circuit was established with 50HP Fan.

Explored return Air shaft in 1A seam and cut off return air ways with temporary stoppings in 1 seam return shaft.

Explored the workings in 1A seam up to 40L including working districts and found normal environmental conditions.

RE-OPENING OF MINE

Explored the 1S 6 panel of 1 seam through 33D tunnel and 31 ½ tunnel.

During the Exploration

1.Roof falls noticed between 18AL to 20 L

2.Cables, belt conveyor and coal burnt in 1S6.

3. 2 SDLs were covered under roof falls in 1S 6.

4. 2 SDLs were drowned in 1S4.

5. Burnt ash was found in 25LN/1S6.

RE-OPENING OF MINE

Isolating of 1S-6 panel from 26L to 13L between 37R and 36R is planned and the stoppings at 26L, 25L, 38R, 37R of 24L,18LN, 14LN, 13LN and 12LN were completed and partially constructed at 23LN/36R.

Due to Intense heat and smoke along 36R further rescue work could not be taken up and decision taken to seal off entire 1 Seam at inter seam tunnels and Up cast shaft below 1 seam.

Accordingly all the entries to 1 seam and Up cast below 1 Seam were closed.

Drilling of up ward bore hole from RK-7 workings to RKNT is under progress for de-watering.

High capacity pumps are being installed for de-watering the mine energizing of the power is under progress.
