Basic Information. CIN Number :. Company Name :. Poor mining methods used are the main cause. After nationalization of coal in , 70 locations of fires were discovered. Jharia coal fields are the only source of coking coal in india and spread over an area of km2 Filling sand, water, and the other methods as removing burning coal have been tried with little success.

According to BCCL Estimates, more than 37 million tones have been devoured by the fire Affects on people- contamination of air and water, release of gases as SO 2 , CO and arsenic, trees and vegetation are affected badly, subsidence occurs, threat to existing roads and railways. Mapping Methods Used Normally following methods are adopted- Temperature measurements of the land surface, in fissures and boreholes, for example using pyrometers Gas measurements to characterize the fire ventilation system amount and velocity and the gas composition, so that the combustion reactions can be described Geophysical measurements on the ground and from airplanes and helicopters to establish the extent of conductivity or other underground parameters.

For example, conductivity measurements map humidity changes near the fire; measuring the magnetism can determine changes in the magnetic characteristics of the adjacent rock caused by heat Remote sensing from aircraft and satellites, High resolution optical mapping, thermal imaging and hyperspectral data play a role.

The objective of project was I. Mitigation Approaches Normally the approach for mitigation includes- In the case of near-surface coal seam fires, the influx of oxygen in the air can be interrupted by covering the area or installing gas-tight barriers.

However, if any remaining dry coal absorbs water, the resulting heat of absorption can lead to re-ignition of a once-quenched fire as the area dries. Accordingly, more energy must be removed than the fire generates Generally all these methods are combined Near-surface coal seam fires are routinely extinguished in China following a standard method basically consisting of the following phases: Smoothing the surface above the fire with heavy equipment to make it fit for traffic.

Drilling holes in the fire zone about 20 m apart down to the source of the fire, following a regular grid. Injecting water or mud in the boreholes long term, usually 1 to 2 years. Covering the entire area with an impermeable layer about 1 m thick, e.

Planting vegetation to the extent the climate allows. As a result of the study following fire control measures were planned- For a fire to initiate and be sustained, three components must be present: fuel, oxygen, and heat. Excavation, blanketing surface sealing , and flooding are the only potentially viable methods available to extinguish a fire in an underground mine, an opencast mine Of the three potentially viable methods, excavation is the only certain means to extinguish a fire McElroy Excavation and cooling the over excavated material to a temperature at which combustion cannot continue is the sole method that can assure a fire has been extinguished.

Surface sealing is a viable fire extinguishment method only when: a the blanket is sufficiently thick to limit air intrusion to negligible levels; b the blanket is noncombustible; c the blanket does not develop fissures from mine-related differential settlement or desiccation or alternatively, is continually maintained to seal off fissures and cracks ; and d there are no underground sources of air to sustain the fire and compromise the effectiveness of the blanket.

Sealing must generally be assumed imperfect Extinguishment by flooding, requires a long term, essentially permanent, raising of the mine pool to dispel latent heat in the rock mass. Short term flooding is generally inadequate for this purpose, but can sometimes be used for containment. Flushing of incombustible granular or grout materials into underground mine workings can theoretically extinguish a fire by sealing off oxygen, but cannot be assumed totally effective because of probable incompleteness of the backfilling process.

Water cannons can be effective in quenching burning material exposed in highwalls or on debris faces immediately prior to excavation.
