Hydro-Mechanical Degradation and Progressive Failure of Sandstone–CGFB Composite Structures Under Cyclic Water Immersion: Implications for Water-Induced Instability Risk in Backfilled Goafs

Sandstone and cemented coal gangue-fly ash backfill (CGFB) form composite load-bearing structures in goafs, where repeated water ingress and drainage may weaken stability. This study investigated sandstone–CGFB composite specimens subjected to 0, 3, 6, and 10 water immersion–dryi...

From microseismic monitoring to targeted reinforcement: a data-driven simulation approach for deep tunnel stability

Deep hard-rock tunnels are highly susceptible to localized rock mass damage under the coupling effects of high in-situ stress and blasting disturbances during construction. The complex spatio-temporal evolution of such damage makes real-time identification and mitigation challeng...

Microscopic interactions and wetting behavior at the micro/nano-bubble water-coal interface: experiments and molecular simulations

Coal seam water injection is a key technology for pre-wetting and dust suppression prior to mining, with its effectiveness largely dependent on the wetting capability of water on coal. As a novel wetting medium, micro-nano bubble water (MNBW) has drawn increasing attention due to...

A Bibliometric Review of Chinese Research on Coal Spontaneous Combustion Inhibitors in Years 1990–2025

To better understand the research status and development trends of coal spontaneous combustion inhibitors in China, this study uses CiteSpace to conduct a bibliometric analysis of relevant literature from the CNKI database (1990–2025). The analysis covers publication trends, inst...

Study on the slurry characteristics and combustion mechanism of modified coal gasification fine slag-coal water slurry

In this study, carbon-rich gasification fine slag (RCGFS) was modified using emulsified asphalt (EA) to produce modified RCGFS (MRCGFS), which was used to prepare carbon-rich gasification fine slag-coal water slurry (MRCGFS-CWS). Concurrently, the slurry formation properties and...

Coupling of wear sensor measurements with numerical modelling for grinding mill charge dynamics prediction

Accurate knowledge of charge dynamics in grinding mills is essential for optimising throughput, energy efficiency, and liner life. However, progressive liner wear continuously alters the internal geometry, making realtime charge prediction challenging. This article presents a nov...

Mechanical properties and fracture failure characteristics of fractured limestone under coupled freeze-thaw and cyclic loading

<title>Abstract</title> The Central Asian Orogenic Belt possesses abundant mineral resources. As mining activities extend into high-altitude cold regions, the safety and stability of rock engineering projects, such as open-pit mine slopes, have become increasingly prominent. This...
