Abstract
The geological information on coal reserves within fields of the Chertinskaya-Yuzhnaya and Chertinskaya-Koksovaya mines situated in the vicinity of an earthquake focus is given. Methane emission in roadways of the mines is determined, and the model diagram of methane concentrations before and after the earthquake is obtained. The earthquake load on coal seams is estimated.
