    06/04/2021· Air blasting in mining is a method of blasting in which compressed air at very high pressure is piped to a steel shell in a shot hole and discharged It is often called air overpressure An air blast is the airborne shock wave generated by an explosion In underground mining, after an explosion a strong rush of air follows Air is also caused by the ejection of air from large undergroundand environments underground which need to be understood, monitored and managed to prevent ignition, combustion or explosion –Methane •Flammable gases are easy ignited and may explode –Liberated Coal Dust •Dust cloud can be formed during blasting process Unacceptable Outcomes from Explosives Use •Ignition of Methane by the Explosive •Ignition of Coal Dust by the explosiveBlasting in Underground Coal Mines Mining Science andThe mining Regulations fix the following limits on the number of shots to be fired by a shot firer Underground Coal Mines: Deg 1 gassy mines – 50 shots with singleshot exploder and 100 shots with multi shot exploder Deg 2 & 3 gassy mines – 40 shots with singleshot and 80Blasting Techniques Used in Underground and Opencast Mines
