Determination of gas content of coal and carbonaceous material - Direct desorption method
Standards Australia
Determination of gas content of coal and carbonaceous material - Direct desorption method
Standards Australia
Specifies procedures for the determination of the desorbed gas content of coal and carbonaceous material by directly measuring the volume of gas, using the water displacement method, from material obtained by coring or collection of lump samples.
This Standard covers the following two direct methods, which vary only in the time allowed for the gas to desorb from the intact sample prior to final crushing:
(a) The slow desorption method.
(b) The fast desorption method.
The Standard is confined to the direct method using lump or core samples.
Desorption limitations to the method are specified in Appendix A.
This Standard does not include the gas content determination using cuttings from drilling and interpretation of the results do not fall within the scope of this document.
