Abstract

The rapid detection of the reasons for mining accidents that lead to emergency situations is vital for search and rescue work. The control of fire and gas leakage provides an immediate approach for rescue works for deaths or injuries and the detection of who needs resuscitation outside of the mine. The evacuation and recovery operations should be directed by continuous monitoring of the mine environment due to fire and explosion risks. The main toxic gases in mines are carbon monoxide (CO) and carbon dioxide (CO2 ); the flammable gases are methane (CH4 ), CO, and hydrogen (H2 ); the suffocating gases are CO2 , nitrogen (N2 0), and CH4 ; and the toxic gases are CO, nitrogen oxides (NOx), and hydrogen sulfide (H2 S).
