Deformation characteristics of surrounding rock of broken and soft rock roadway

Mining Science and Technology, 2009
Abstract 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 ...

Testing of Strength Parameters and Deformation Parameters of Surrounding Rock and their Distributions

Advanced Materials Research, 2011
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 ...

Forecast Study on Large Deformation of Surrounding Rocks in Mountain Tunnels

Applied Mechanics and Materials, 2012
Shilin tunnel is a separated bi-directional four-lane highway tunnel, and its distinctive geological conditions and fault structure result in frequent geological disaster like large deformation. Construction of tunnels were seriously hampered, and the project was delayed, and the cost increases simultaneously.
