The aforementioned experimental results at macroscopic scale demonstrate that injecting CO2 or N2 into coal seams can effectively displace the otherwise difficult-to-desorb CH4, providing experimental evidence that gas injection displacement technology represents an effective approach for gas hazard control. However, since the coal samples used in laboratory experiments were significantly smaller than actual coal masses in underground mines, it is necessary to conduct engineering-scale field applications of underground gas injection displacement for coalbed CH4 to validate the technology’s effectiveness in gas hazard prevention.

摘要

The aforementioned experimental results at macroscopic scale demonstrate that injecting CO2 or N2 into coal seams can effectively displace the otherwise difficult-to-desorb CH4, providing experimental evidence that gas injection displacement technology represents an effective approach for gas hazard control. However, since the coal samples used in laboratory experiments were significantly smaller than actual coal masses in underground mines, it is necessary to conduct engineering-scale field applications of underground gas injection displacement for coalbed CH4 to validate the technology’s effectiveness in gas hazard prevention.
