Methane ignition by frictional impact heating.
Combust Flame 1975; 25(2):143-152
As part of a program conducted by the Bureau of Mines to reduce the explosion hazard in coal mines, a study was made of the frictional ignition source that can develop to cause the ignition of methane when a coal mining machine encounters rock strata or hard inclusions. Such impacts between metal and rock reproduced by a laboratory machine caused a number of ignitions. A model is proposed that considers the mechanisms of energy dissipation during tangential impact.
