| Abstract: | To improve the hole-sealing technology of gas drainage in the coal mine，contrast analysis was carried out between the design of layer-through borehole and boreholes along seam，and the traditional process of sealing. Several new technologies were proposed，including the seam three segment polyurethane mortar combined with pressure，borehole sealing device on working face，and two segment polyurethane mortar sealing and other new technology. Practical application shows that，the application of new technology can improve the concentration of gas drainage，and prolong the time of drainage. It also has solved many problems in hole-sealing，and has ensured the successful and safe gas drainage work in coal mine. |
