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 …

Coal burst has become a common safety issue in underground coal mines and its triggering
mechanism is believed to be highly associated with coal state parameters including stress …

Natural processes are known to cause significant damage to archaeological monuments. In
fact, the key to understanding the decay of building materials is the internal movement of …

Three-dimensional velocity tomograms were generated to image the stress redistribution
around an underground coal longwall panel to produce a better understanding of the …

Generally, knowledge of stress redistribution around the longwall panel causes a better
understanding of the mechanisms that lead to ground failure, especially to rockbursts. In this …

Monitoring and early‐warning are critical for the prevention and controlling of rock burst in
deep coal mining. In this study, rock burst risk assessment criterion was built based on the …

This study uses an extensive suite of borehole pressure cell (BPC) data from a US longwall
mine to better characterize the global stress redistribution process during mining. A new …

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 …

基于近年来在多个采煤工作面开展的实测研究结果, 论述了地震CT 技术在采煤工作面进行不同
目的探测时的应用原理, 方法及解释原则. 研究表明: 基于地震波波速异常率分布可以对工作面 …

Mining-induced stress-field changes pose both safety and economic hazards. In an effort
aimed at developing technology for mitigating such hazards, the Bureau of Mines together …
