The effect of different gases on the ultrasonic response of coal

To gauge the potential of seismic methods for the estimation of gas content in coal, the ultrasonic response of a sample saturated in turn with He, N2, CH4, and CO2 has been investigated. Specifically, traveltimes were used to determine P-wave velocity as a function of the difference between confini...
