| Abstract: | To overcome floor heave problems associated with deep high-stressed soft rock of auxiliary mine shafts in Panyi Coal Mine East effectively,the major affecting factors of chamber floor heave were analyzed based on character and in situ stress state of surrounding rock.Combining with numerical simulation,the control scheme that combining overbreak back-filling with deep-hole cable routing to control floor heave was proposed in this paper.Field experiment shows that,the scheme has effectively controlled the fl... |
