Research on Supporting Technology of Wind Drift at B103W01 Workface in ShajiHai Coal Mine

Abstract:

The deformation and failure problems in soft rock supporting cannot be effectively controlled with conventional methods. This paper put forward the coupling support technologies by the use of large deformation constant-resistance bolt, large deformation constant-resistance cable and bottom-grouting pipes, with the analysis of deformation and failure reseasons, combing with verifications in field-test project at B103W01 working face, State Grid Energy abundance Coal Limited Shajihai Coal Mine. It also provides the reference for the tunnels supporting under similar conditions.
