| Abstract: | In order to solve the safety issues of roadway excavation caused by crossing especially big outburst holes of Anwen inclined shaft in Tonghua coal mine,the technology of crossing especially big outburst holes was researched based on comprehensive technique of "sealing + grouting + interception hole + metal skeleton".Adopting the construction method of arched temporary support combining with shallow tunneling and shallow advancing,and the final permanent support with concrete body,the technology of crossing holes is elaborated,which achieves the safety tunneling of especially big outburst holes. |
