Borehole seismic methods for opencast coal exploration [PDF]

, 1990
Surface seismic techniques lack the resolution to image the top 100m or so of the earth's surface necessary for opencast coal exploration. The work reported in this thesis is the development of borehole seismic methods making use of the closely spaced ...

Effects of mining subsidence observed by time-lapse seismic reflection profiling [PDF]

, 1995
Extracting coal from underground mineworkings causes the overlying rocks to subside with associated changes in the stress regime. The aim of the study reported here was to apply the surface seismic reflection method to study the effect of subsidence on ...

Shaking Table Test on Liquefaction of Sandy Soil Site and Sensitivity Analysis of Liquefaction Influencing Factors

Eng
Earthquake-induced soil liquefaction poses a severe threat to the structural safety of underground infrastructure. This paper presents a shaking table model test conducted on sand sites, where two site models—namely, uniform saturated sand and layered ...

A Parametric Study of Nonlinear Seismic Response Analysis of Transmission Line Structures

The Scientific World Journal, 2014
A parametric study of nonlinear seismic response analysis of transmission line structures subjected to earthquake loading is studied in this paper. The transmission lines are modeled by cable element which accounts for the nonlinearity of the cable based
