Abstract:Methane explosion
is an undesired incident in the coal
mining industry.
Its high pressure wave can cause damage to the rock mass. This study
numerically investigated the flame and wave transport characteristics
of methane explosion with ignition sources at three different locations,
and the corresponding dynamic response of the rock masses was discussed.
The results showed that the flame propagation time is shortest when
the ignition position is located at the center of the H-type roadway
structure and the max… Show more
