... seam in front of a working face is an essential factor to produce the rational strata response. The strata can fail in front of the working face or over the goaf controlled by the yield degree of coal seam. The bending moment magnitude of strata is significantly influenced by both the support scheme...

... of the specific location is large; corresponding anchor bolt force is relatively large. The force distribution of the systematic bolts and cables after the final excavation shows that the supporting system is safe under the support scheme of construction. The parts closing yield state mainly distribute...
