| Description |
Improvement in climatic conditions at workings in mine having surface cracks by increasing fan capacity is a risky proposition. It may lead to spontaneous heating in the mine due to leakage of air from surface caused by increase in cumulative pressure drop measured from the surface. The above problem cannot be addressed by conventional ventilation system.
Anew method of ventilation named "Chamber method of ventilation" have been evolved to ventilate the workings under the situation mentioned above, the method is superimposed on the existing ventilation system of the mine without much modifications or any adverse effect on ventilation of remaining districts. The method was successfully implemented at 1 & 2 incline mines, Jhanjra project, Eastern Coalfields Limited (ECL) to reduce surface air leakage for control of fire in a working longwall panel and for improvement in climatic condition.
