In this study, the effect of gradual deterioration on the long-term stability of shallow
abandoned room and pillar coal mines is investigated. The conventional Tributary Area …

Abandoned underground mines remain insufficiently investigated landforms, which leads to
underestimating their importance within world landscapes. Even though they stand as …

While tunneling through Tertiary sandstones in Taiwan, tunnel squeezing occurred in some
of the sandstones (eg, Mucha Tunnel and Chungho Tunnel in northern Taiwan), but not in …

The time-dependent stability of tunnels is an important and challenging topic, mainly when
the tunnel is excavated in incompetent and weak rocks. The creep property of rock is one of …

Post-mining subsidence is a serious problem in urban areas constructed above abandoned
mine workings. Subsidence may severely damage the environment and threaten the stability …

Static fatigue of a polycrystalline porous rock (iron ore) was studied by performing multistep
uniaxial creep tests under partially saturated conditions, and the impact of water saturation …

The viability and success of a deep mining or tunnelling project is dependent on a safe,
reliable support design. In highly-stressed brittle rock, this design must properly account for …

This paper deals with the development of a non-linear constitutive model of a rock mass and
its application to predict the extension of the excavation damaged zone (EDZ) around …

In chalk mines, the method of room and pillar mining has been widely used in France. Yet,
many large collapses have occurred during or after their exploitation, with the collapse of …

On basis of triaxial creep experimental results of coal with various deviatoric stress levels, a
new nonlinear visco-elastic and accelerating creep model is put forward. First, Burgers visco …
