| Abstract: | This paper makes an earnest analysis of the release zone,stress distribution on stress concentration belt and the reason of deformation on the ahead of the 0908 fully-mechanized coal bed.It uses the method of drilling negative pressure to determine the radius of gas drainage and accounts the the necessary equipment and measuring steps of this method in detail.And it determines the radius of gas drainage by field testing.This provides reasonable basis for the design of the gas drainage drilling interval on the release zone and ensure the safe production of the mining face. |
| Keywords: | method of drilling negative pressure determine radius of gas drainage |
