Strata behavior regularity and plugging technology of fully mechanized face corner in high gassy seam
In order to resolve the problem that single hydraulic prop and glue woven bag full of crushed coal or broken bottles are piled up to sealed goaf, decrease the labor intensity of the workers, increase support efficiency.At the same time, roof caving is most likely to transpire, the upper corner gas concentration too large.The workers personal safety constitutes a great threat.So airbag stent was invented, and the experiments were finished to test the performance.The experiments and underground test showed that the airbag met the needs of design and production.
upper corner and down-corner angle the airbag stent plugging methane
