The Sensitivity Study on Influencing Factors of Fracture Development the Depth in Stope Floor Rock
Abstract：Floor water invasion process actually is rock crack Initiation and extended and transfixion by water drive,and until Fracture lead to Instability.this paper design 9 calculation models by orthogonal test,and do range analysis about UDEC calculation results,and obtain the sensitivity sequence that is on influencing factors of the fracture development depth in coal bed floor rock is aquifuge strength rock stress preexisting fissures degree mining faces length artesian pressure mining height.The result can qualitative discriminate the fracture development depth in Coal bed floor rock on the Top of water-pressured.
