Determination of Trace Elements in Magnetite by Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry Using Multiple External Standards without an Internal Standard Calibration

Yankuang ceshi, 2016
Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry (LA-ICP-MS) is commonly used to analyze trace elements in magnetite, which can be divided into internal standard (IS) and no internal standard (NIS) methods according to calibration techniques ...

Rock magnetic and geochemical evidence for authigenic magnetite formation via iron reduction in coal-bearing sediments offshore Shimokita Peninsula, Japan (IODP Site C0020) [PDF]

, 2017
Sediments recovered at Integrated Ocean Drilling Program (IODP) Site C0020, in a fore‐arc basin offshore Shimokita Peninsula, Japan, include numerous coal beds (0.3–7 m thick) that are associated with a transition from a terrestrial to marine ...

Blasting effects of cross‐fault deep‐buried excavation on adjacent existing tunnel stability

Deep Underground Science and Engineering, EarlyView.
Based on the theoretical analysis of cylindrical wave propagation in a deep rock mass in the fault with a filling layer, the calculation method of peak particle velocity caused by wave propagation in the existing tunnel is established. The viscoelastic characteristics of a rock mass are examined in the analysis.

Failure mechanism of the coal wall at the working face based on an eccentric compression mechanical model

Deep Underground Science and Engineering, EarlyView.
In this study, the nonuniform distribution of the bearing pressure in front of the coal wall has been revealed based on in situ monitoring data and numerical simulation results. Therefore, an eccentric compression mechanical model of the coal wall was established to study the deformation and failure characteristics of a coal wall. The slenderness ratio
