Studies of a three-stage dark matter and neutrino observatory based on multi-ton combinations of liquid xenon and liquid argon detectors [PDF]

, 2012
We study a three stage dark matter and neutrino observatory based on multi-ton two-phase liquid Xe and Ar detectors with sufficiently low backgrounds to be sensitive to WIMP dark matter interaction cross sections down to 10E-47 cm^2, and to provide both ...

A self-supervision rockburst risk prediction algorithm based on automatic mining of rockburst prediction index features

Frontiers in Earth Science
The rockburst risk prediction based on microseismic (MS) data is an important research task in deep mine safety prevention. However, the lack of systematic research on explicit prediction indexes and the waste of a large amount of unlabeled data are ...

Shattering Rock with Intense Bursts of Energetic Electrons [PDF]

IEEE Transactions on Nuclear Science, 1973
It has been successfully demonstrated that intense bursts of energetic electrons cause significant rock spalling for modest energy inputs. The corresponding temperature rise per pulse in the bombarded volume of rock is only ~ 200° C, or so. Some analytical predictions and experimental evidence of this novel accelerator application are presented.

Upward Tau Air Showers from Earth

, 2004
We estimate the rate of observable Horizontal and Upward Tau Air-Showers (HORTAUs, UPTAUS) considering both the Earth opacity and the finite size of the terrestrial atmosphere.

Experimental and numerical study on rock burst triggering mechanism via spatiotemporal evolution of stress flow

Meitan kexue jishu
To address the prevention and control of rock burst disasters in deep coal mines, this study focuses on the spatiotemporal evolution mechanism of mining-induced stress, introducing the novel concept of “stress flow” to characterize dynamic stress ...

Predicting Rock Bursts in Rock Mass Blocks Using Acoustic Emission

Resources, 2022
Geophysical methods for local rock burst prediction are currently being developed along two lines: improving recording equipment and improving data processing methods. Progress in developing processing methods is constrained by the lack of informative prognostic models that describe the condition of rock mass, the process of rock mass fracturing, and ...
