| Abstract: | The reasonable depth of sealing hole is not only an important part of gas drainage,but also a key to improve the efficiency of the gas drainage.In this paper,a reasonable determination of the "three zone" was used to test the 1117(3) face in Guqiao mine.At last,the logical depth of sealing hole of the coal seam gas drainage was obtained through the simulation of numerical simulation software,which lay a solid foundation on the efficient gas drainage. |
