Abstract: To explore the gas extraction effect under multi field coupling conditions,a gas extraction test model was established using COMSOL software.Taking Yulong Coal Mine as an example,the evolution trends of temperature,gas pressure,and permeability with extraction time were analyzed,and the gas extraction effects of three hole and rectangular hole layout methods were compared and analyzed.The results show that temperature,gas pressure,and permeability show a decreasing trend with the extraction time,and the degree of change is most significant under the condition of extraction time of 50-90 days.It is recommended that 90 days be used as the governance time limit for gas extraction in Yulong Coal Mine.The effective extraction radius of the triplet eye layout way is larger than that of the rectangular layout way,with a year-on-year increase of 0.82 m.
