Abstract:
1. A system for testing gas migration process in coal-rock mass, comprising: a loading system, for applying an axial pressure and/or a radial pressure to a coal sample under sealing state so as to desorb the gas absorbed in the coal sample; a temperature control system, for controlling a temperature of the coal sample under the sealing state so as to desorb the gas absorbed in the coal sample; a gas composition detecting and measuring system, for detecting pressure, composition, flow rate and content of each composition of the gas desorbed from the coal sample; and a data acquisition instrument, for collecting data outputted from the gas composition detecting and measuring system, as well as analyzing, comparing and summarizing the outputted data; wherein the gas composition detecting and measuring system is connected to the loading system via a guiding passage, and the data acquisition instrument is electrically connected to the gas composition detecting and measuring system.
