Organic Nanoaerosol in Coal Mines: Formation

2017-6-30  This fact confirms the thesis that the release of frictional heat is the driving force for the formation of organic aerosol. The analysis of gas-phase products in the outflow of the grinding machine showed that along with aerosol formation, gas products such as CO, CO2, CH4, C2H6, H2O are released from coal due to the frictional heat.
