Deformation characteristics of surrounding rock of broken and soft rock roadway
Mining Science and Technology, 2009Abstract A similar material model and a numerical simulation were constructed and are described herein. The deformation and failure of surrounding rock of broken and soft roadway are studied by using these models. The deformation of the roof and floor, the relative deformation of the two sides and the deformation of the deep surrounding rock are ...

MOVEMENT AND DEFORMATION CONTROL IN SURROUNDING ROCK MASS
News of the Tula state university. Sciences of Earth, 2023The paper describes implementation of geomechanical monitoring of movements and deformations in rock mass and mine structures in hybrid open pit/underground mining. The case-study of extraction ofAikhal kimberlite pipe reserves under bottom of an open pit ofAL- ROSA allows examining the pitwall rock mass stability control using subsurface check points ...

Effect of Water on Tunnel Face and Surrounding Rock Deformation
Indian Geotechnical Journal, 2021To keep construction safe in water-rich stratum is one of the most challenging problems faced by tunnel designers and constructors. In this paper, the Shuiqing Tunnel, as for the engineering background, is located in Bijie-Zhenxiong Highway, Guizhou Province, China. The New Austria Tunneling Method is adopted.
