Abstract: In this paper,comparison was made on the gas drainage rate with the gas content in five different situations in order to determine the gas drainage radius by boreholes,the total gas volume need to be drained was determined according to different drainage objectives,and based on the average gas drainage volume by a single hole in a certain period of time, the number of boreholes need to be laid out in the gas drainage area was calculated and then the gas drainage radius by boreholes was obtained. Through the comparative analysis, actual inspection and fitting calculation, an effective gas drainage radius by boreholes in a certain period of time was determined. The practice showed that it is feasible to use the gas content method to determine the gas drainage radius by boreholes.
