Grisou

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)... [Pg.145]
