ln order to solve the problem that the gas pressure measured value was too low caused by many cracks,borehole not uly sealed and the air leakage of the measured borehole during gas pressure measuring period in the coal and gas outburst mine of Changcun Mine, an indire。t method of gas pressure growth curve was applied to measure gas pressure.Meanwhile,a comparison analysis was conducted to the gas pressure measured with the direction method,the method was applied to the engineering practice measurement in Changcun Mine. The study results showed that the max seam gas pressure measured with the direction method was 0.61MPa,the seam gas pressure measured with the gas pressure growth curve method was 0.92 MPa,the pressure measured with gas pressure growth curve method was 0.31MPa higher than the direction method.The application showed that the gas pressure measured with the gas pressure growth curve method could be more acurate to the actualvalue and would have important significances to guarantee the mine safety production.
