In order to improve the stability of the stent during the mining period,reduce the stent tilt inverted frame phenomenon,now combined with the field over the fault test and the stability of the stent in the normal mining of large inclined angle working face to carry out a comprehensive analysis,through the application of the field,the results show that,the selection of model ZZ8400/21/48,the critical tipping support resistance of 6,980.81 kN,slip support resistance of 5,979.21 kN of the Hydraulic support,during mining large inclined angle working face over fault,the stability of the support is greatly improved,and the problem of support instability in the construction process is solved.
