Abstract: In the coal mining operation, the gas prevention and control work is very important, and it is related to the life safety
of the personnel in the mine. Underground ventilation is the key of gas control. Starting with the U type ventilation of working face
upper corner, the paper discusses how to do well in the gas control measures of the upper corner of the working face, to make downhole
operation in safe and stable environment. Key words: air velocity; draw off device; pressure difference
