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 ...

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 ...

Cores were taken from the hanging wall of the III -1 ore body at Kangjiawan Lead, Zinc and Gold Mine. 50 samples for compression and tension tests were fabricated. 50 compressive and 50 tensile strength values were obtained by RMT-150B testing systems. The probability distributions for the compressive and tensile strength were tested by the hypothesis ...
