Investigating the wetting effectiveness of surfactant blends on anthracite coal dust: combined experimental and molecular simulation approaches

Abstract Conventional water spraying methods often prove inadequate due to the poor wettability of these coal dust particles. To address this, the present study introduces a comprehensive strategy that integrates molecular dynamics (MD) simulations with laboratory experiments to...

Energy evolution laws and acoustic emission damage characteristics of coal-rock combinations with different lateral unloading rates

In deep coal mining, excavation-induced lateral stress unloading can trigger rapid stress redistribution and energy release in coal-rock combination, resulting in dynamic hazards such as rock bursts. However, the rate-dependent damage mechanism and energy evolution characteristic...

Ensemble stochastic configuration networks modeling method for short-term wind speed prediction and noise reduction

Considering complex problems such as extreme weather and equipment failure, the wind speed information collected by the sensor are often contaminated some noise information, which directly affects the modeling accuracy of the wind power prediction problem. In order to solve such...

Normal-stress unclamping promotes cascading instability in deep mining-induced seismicity

Deep mining-induced seismicity poses a severe dynamic hazard and offers a near-field setting for examining fault interaction under rapidly evolving excavation-induced stress fields. Conventional stress-concentration frameworks may overlook failure paths governed by normal-confine...

Optimization of the Symbiotic System Between Sulfate-Reducing Bacteria and Sulfide-Oxidizing Bacteria and Study on the Mechanism of Repairing Acidic Mine Drainage

Acidic mine drainage (AMD) rich in heavy metals and sulfates causes severe environmental hazards. SRB and SOB are ideal remediation strains, yet their microaerophilic symbiotic metabolism and metabolite characteristics remain ambiguous. This study explores their symbiotic metabol...

StructuralDiversity and Multicenter Bonding in Beryllium–OsmiumIntermetallic Compounds

Abstract Beryllium intermetallic compounds (beryllides) have attracted considerable interest for applications relevant to nuclear systems, refractory materials, and aerospace systems due to their exceptional physical properties. In this work, crystal structures of osmium beryllid...

High-Precision Visual Absolute-Localization Method for Deep-Space Probes Based on Salient Landmarks

To address the scarcity of high-precision control points on planetary surfaces and the accumulated drift of conventional relative-localization methods in deep-space exploration missions, this paper proposes a visual absolute-localization method based on salient-landmark contour m...

Axial compressive behavior of coal gangue concrete-filled composite steel tube stub columns

This paper presents a numerical investigation on the axial compressive behavior of composite steel tube coal gangue concrete (CG-CFCST) stub columns, in which an outer circular steel tube and an inner circular steel tube confine a sandwich layer of ordinary concrete and a core of...
