Due to high metal prices and increased difficulties in finding shallower deposits, the
exploration for and exploitation of mineral resources is expected to move to greater depths …

Reconciling roof fracturing and the induced rockburst damage has long been an issue in
deep coal mines [1],[2],[3]. Especially for hard–brittle–thick roof strata in overlying rock …

Seismic measurements take many forms, and appear to have a universal role in the Earth
Sciences. They are the means for most easily and economically interpreting what lies …

In order to analyze the microseismic (MS) effects of hard and thick igneous strata separation
and fracturing and the corresponding evaluation index of fracturing intensity, the temporal …

Cases of rockbursts were investigated to analyze the influence of syncline structures on
rockbursts. In a syncline structure in Xing'an Coal Mine, the relationship between the activity …

Coda waves are highly sensitive to changes in the subsurface; we use this sensitivity to
monitor small stress changes in an underground mine. We apply coda wave interferometry …

In an effort aimed at monitoring mining-induced stress changes that may influence ground
failure, the US Bureau of Mines conducted a series of active 3-D seismic tomographic …

We conducted three-dimensional passive seismic tomography surveys by using mining-
induced seismicity of a deep nickel mine. To investigate the stress evolution with the …

Anomalous information identification is a key issue for seismic hazard prevention in
underground mining. Velocity tomograms can image the stress redistribution around coal …

In recent years, along with the innovation of coal mining process and equipment in China,
such as the advanced combined support system composed of pre-tensioned bolting and …
