Gas-Bearing and Gas-Saturated Coking Coal

Аннотация

The properties of Zh and K coal are investigated in the mine and in the laboratory. Some coal samples are saturated with methane in the laboratory, after complete gas removal. The gas content differs in natural coal and in coal saturated with methane in the laboratory, on account of differences in the state of coal and methane in the bed and in an artificial sorbent–sorbate system.
