GB/T 23250-2009 The direct method of determining coalbed gas content in the mine
Abstract
This standard specifies the sampling method for directly measuring the gas content in coal seams underground, the method for determining the amount of desorbed gas, the method for compensating for the amount of lost gas, the method for determining the amount of residual gas, and the method for calculating the gas content in coal seams.
This standard is applicable to the direct measurement of gas content in coal seams using the desorption method in coal mines.
This standard is not applicable to drill holes with severe water leakage, drill holes with gas emission, and the determination of gas content in core samples.
