Poor visibility caused due to emission of suspended particulate matters (SPM) during open fires in underground coal mines generally dampened the fire fighting and rescue operations. Three sets of experiments at varied airflow rate, carried out in the CMRI mine fire model gallery, indicates that the open fires can cause more than 90% opacity, hence severely affects the visibility in the mine. Emission rate of SPM increase with the increase in air velocity while its concentration in the fire area depicts the opposite trend. Application of fire suppression techniques like LN2 and HPHS nitrogen foam slightly improves the visibility but water mist is most effective in improving the visibility during open fires condition.
