| Abstract: | This article focuses on the current problem of predicting coal and gas inrush and will carry out several on- location drilling tests of differring varieties and depths.Furthermore,this article will study the feasibility of shallow hole prediction by using the drilling gas inrush initial velocity method (q value).Through the utilization of actual data curve variation of differing hole depths,the critical value of the testing depth and inrush can be determined. |

| Keywords: | shallow hole prediction gas inrush initial velocity inrush critical value |
