Spontaneous combustion of coal and its early detection in okr mines

Assessment of indicator gases of spontaneous combustion in

In OKR for temperature estimation of the centre of spontaneous combustion both can be used today: estimation according to initial occurrences of indicator gases, e.g. Fig.1 and according to their a...

Assessment of susceptibility of coal to spontaneous combustion in

A brief overview of development in the use of indicator gases for

coal, CO was released and oxygen concentration decreased depending on the temperature of oxidized coal. His research led to the development of a method based on the determination of two basic index...
