Drilling drainage influence radius is crucial for the selection of drainage method,the parameters of drill holes layout and the test of drainage effect,whose determination accuracy is significant to gas drainage in mines.In view of the actual situation in Luling Colliery and through the analysis of the drainage radius testing method and principle,the authors make an experimental research on gas drainage radius in No.8 coal seam by pressure drop method,whose results show that the pressure drop method plays a role in determination of drilling drainage influence radius,provides a scientific basis for the design of drainage borehole and improves the gas drainage effect.
