Another Commission was appointed in France to inquire into coal-mine explosions. Influenced by Berthelot s work and theories, its attention was directed to the question of the heat evolved by an explosive and the resulting temperature of the products (Ref 11, p 45) Note I As a result of the work of the Commission, a max temp of 1500°C for expls used in coal layers (explosifs grisou-couche) was established and 1900°C for expls used for blasting rock in gaseous coal mines (explosifs grisou-roche) (Vol 3 of Encycl, p C369-L)...

Modern coal-mining practice tends towards the use of mechanical devices, such as Cardox, Hydrox Mechanical Miners rather than explosives. This will not necessarily reduce the number of coal mine explosions because these may be, and indeed are known to be, initiated by other means such as faulty electrical equipment, breakage of electrical cables or other means of producing a hot spark or arc...
