Abstract：In this paper, the application of Tiangu hole-sealing material in Huainan Xiejiaji No. 1 Mine was described, its comparison with the traditional cement mortar was made, and analysis was carried out on the hole-sealing performance of Tiangu material from the gas drainage concentration by boreholes, the gas concentration distribution and the degree of gas concentration decay. The results indicated that the average gas drainage concentration from the holes sealed with Tiangu material was 85. 1%, and that from the holes sealed by cement mortar was only 45. 6%, the hole-sealing effect of Tiangu material was more stable and the degree of gas concentration decay is much small.
