Flawed coal is the most common construction object in the mining process, and
understanding its mechanical behavior and damage evolution is crucial for monitoring the …

Abstract Development of the deformation monitoring techniques for the infrastructures so as
to avoid catastrophic failure and resulting economic/human loss has remained a key interest …

Precursor information of rock fracture is a prerequisite for rock dynamic disaster (RDD)
prediction. To investigate the precursor information of rock fracture based on pressure …

This paper presents a fractal analysis of the ULF electromagnetic data obtained at Guam
observatory during a strong (Ms= 8.0) earthquake occurred on August 8, 1993 near the …

This book deals with the electromagnetic fields observed on the ground and in space in the
ULF (ultra low frequency, f< 3 Hz) and ELF (extremely low frequency, 3< f< 3 103 Hz) bands …

The combination of acoustic emission and electrical potential monitoring methods holds
promise for monitoring and warning of rock bursts due to its comprehensive reflection of the …

The generation of transient electric potential prior to rupture has been demonstrated in a
number of laboratory experiments involving both dry and wet rock specimens. Several …

Weak currents can be stimulated from coal and rock materials under a load. To investigate
the response characteristics of weak current to coal failure and mine seismicity, both …

Rock failure can cause serious geological disasters, and the non-extensive statistical
features of electric potential (EP) are expected to provide valuable information for disaster …

The pressure stimulated currents (PSCs) and acoustic emissions (AEs) simultaneously
emitting from rocks during deformation and fracturing are gradually receiving attention for …
