Optimisation of Support Parameters of Tape Alley over Faults in a Mine in Shanxi,China
Aiming at the problem of large deformation of single-day subsidence of the roof plate in the fault section of No.15 coal seam west tape lane(both:15106 transport lane)of a mine in Shanxi,the original support parameters were optimised according to the engineering geological conditions of the fault section of the west tape lane.The results show that:after the optimisation of the fault support parameters,the deformation of the top plate of the No.15 coal seam west belt roadway is 12.5 mm and the deformation of the bottom plate is 25.6 mm,the deformation of the two gangs of the No.15 coal seam west belt roadway is 13.6 mm,and the deformation of the working face gang is 32.5 mm,and the deformation of the peripheral rock damage has been effectively controlled,which shows the reasonableness of the support technical parameters.
