A method for measuring an extraction influence radius based on bedding drilling gas emission characteristics comprises the following steps: 1) drilling observation holes; 2) measuring an initial gas emission amount of each observation hole, then constructing extraction holes, extracting by a networking manner after sealing all the observation holes and the extraction holes; 3) measuring a gas emission amount of each observation hole, then drawing a gas emission amount change curve; 4) applying a regression analysis to the gas emission amount change curve of each observation hole; 5) basing on the regression analysis result and a gas emission amount overall change curve; 6) figuring out a gas emission amount attenuation factor for the later period; and 7) determining a gas extraction influence radius. On one aspect, the method for measuring the extraction influence radius based on the bedding drilling gas emission characteristics overcomes the defects that the gas pressure value is difficult to measure, and an error between the real value and the measured value exists; on another aspect, the method for measuring the extraction influence radius based on the bedding drilling gas emission characteristics overcomes the defects that the gas tracing method is greatly influenced by manual operations, is low in reliability and is high in cost. Meanwhile, the problem that the model constructed by computer simulation method is too ideal is reduced. The method for measuring the extraction influence radius based on the bedding drilling gas emission characteristics is simple in operation, accurate in measurement, and substantially short in time consumption.
