Structure and deformation measurements of shallow overburden during top coal caving longwall mining
International Journal of Mining Science and Technology, 2017 Mining induced pressures are strong and overburden failure areas are large in top coal caving longwall mining, which constrains high production and safety mining. By employing the combination of the full view borehole photography technique and the seismic CT scanner technique, the deformation and failure of overlying strata of fully mechanized caving ...

Mechanism of stress-loaded rockburst in fully mechanized top-coal caving stope with deep overburden
Meitan xuebao, 2023 The stress-loaded rockburst is a unique type of rockburst that occurs in some fully mechanized top-coal caving stopes with deep thick overburden, its occurrence mechanism is still unclear, leading to the failure to effective prevention and even serious ...

Cosmic muon flux measurement and tunnel overburden structure imaging [PDF]
Journal of Instrumentation, 2020 We present a cosmic ray muon tomographic experiment for measuring the muon flux and imaging the tunnel overburden structures in Changshu, China. The device used in this study is a tracking detector based on the plastic scintillator with SiPM technology, which can be conveniently operated in field works.
