In order to solve the problem of coal spontaneous combustion during gas drainage, No.2421 fully mechanized working face in Baijigou Coal Mine was taken as a study object.Based on the numerical simulation,the air leakage field and oxygen concentration distribution law in goaf were researched.Combined with the underground actual situation,the prevention and con-trol technology was determined for coal spontaneous combustion during the gas drainage.
