| description | The invention belongs to the technical field of gas extraction. According to the self-adaptive grooving method and system for the underground coal mine gas extraction drill hole sealing section, a self-adaptive grooving device is used for conducting grooving and seam forming in a deformed extraction pipe of the underground gas extraction failure drill hole sealing section, and an annular seam groove and a spiral seam groove are formed in a grouting hole sealing section in the middle of an original hole sealing section; the self-adaptive grooving device can be automatically adjusted according to the deformation condition of the extraction pipe and is always located in the middle of the extraction pipe, it is guaranteed that high-pressure abrasive water jet conducts grooving and seam forming on the extraction pipe, a solidified hole sealing material and a coal rock mass of an original hole sealing section of a drill hole in the annular and spiral directions, so that annular and spiral seam grooves are formed, a |
