Iron Energy Carrier: Experimental Characterisation, Combustion Diagnostic and Benchmarking with Other Clean Metal Fuels

Energy Science &Engineering, Volume 14, Issue 8, Page 3862-3877, August 2026.
This study investigates how iron particles burn across a wide size range, revealing late‐stage nanoparticle release and a previously unrecognised shift in combustion behaviour near 118 µm. High‐speed imaging, PMT diagnostics and SEM analyses have been conducted.

Research on gas tracing technology of combined drainage in close distance outburst coal seam group

Meikuang Anquan, 2022
In order to solve the problem of gas measurement in combined drainage of close outburst coal seams, taking Nenghua Xiaotun Coal Mine in Guizhou Province as the engineering background, the method of combining carbon isotope method and stratified measurement is proposed to determine the proportion of gas drainage in any coal seam group, so as to provide ...

Research on the Critical Mechanical Criterion for Stick‐Slip Instability of Mining‐Affected Normal Faults Based on the Rate‐and‐State Friction Law

Energy Science &Engineering, Volume 14, Issue 8, Page 3935-3947, August 2026.
Mining disturbance tends to trigger fault stick‐slip instability and induce disasters. This paper establishes a mechanical model to propose a critical criterion, which is verified to be reliable via FLAC3D, providing a theoretical basis for early warning of fault slip disasters.

Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

Sedimentology, Volume 73, Issue 5, Page 1750-1798, August 2026.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

Fracture activation in the overburden and aquiclude stability under the mining of close-distance coal seams

Meitian dizhi yu kantan
BackgroundIn the Jurassic coalfield of northern Shaanxi Province, the repeated mining of close-distance coal seams exacerbates the activation of fractures in the overburden. This is prone to cause aquiclude instability, leading to groundwater loss. MethodsThis study aims to reveal the characteristics of fractures in the overburden and the aquiclude ...

Stress superposition characteristics and roof structure control of recovery room in close distance coal seam

Meitan kexue jishu
The stress disturbance and complex roof situation of the pre excavation recovery room of the close range coal seam group result in severe damage to the surrounding rock of the tunnel during the construction of the recovery room, making it difficult to control the surrounding rock.
