| Abstract: | In view of the technical problem in outburst coal seam gas extraction drilling and sealing site, guided by driUing and sealing technology theory, and taking Tianrong No.1 Mine as the research background, some common hole sealing techniques are compared and studied in this paper. In downhole site implementation process, the sealing construction technology is further improved. The research results show that the sealing quality is ensured and the gas drainage concentration is effectively improved. |
