Thanks to its non-destructive, high-resolution imaging possibilities and its sensitivity to both
conductive and dielectric subsurface structures, Ground-Penetrating Radar (GPR) has …

During the rock tunnel construction, one of the critical aspects lies on the support design to
secure the construction safety. Due to the extreme complex underground geological and …

Abstract Knowledge of the degree and depth of the excavation damaged zone (EDZ)
resulting from drill-and-blast excavations has important influences on the design and …

Destressing and preconditioning of the rock mass through blasting or excavations is an
important ground control technique that results in a release of stored energy and the …

Top-coal structure detection is an important basis for realizing effective mining in fully
mechanized cave faces. However, the top-coal structure is very complex and often contains …

With changes in mining depth, the dynamic mechanical characteristics of the same type of
rock also change, so that the blasting excavation process must be constantly adjusted and …

Stope design is an important part of mine planning, and it aims to balance ore recovery, ore
dilution, and production costs without compromising the safety aspects. This paper …

This chapter scrutinizes the effects of vibrations stemming from various anthropogenic
activities, including dredging, exploration, transportation, and drilling, on benthic …

Fracture zones in front of tunnel faces can easily cause falling blocks and landslides during
the construction process. Using seismic waves and ground-penetrating radar (GPR) data …

A study on the characterisation of rock fracturing ahead of the preconditioned mining faces
in a hard rock mining is described. The study involves the use of borehole periscope, ground …
