Recycling municipal solid waste incineration fly ash and Si–Al based solid waste to prepare backfill materials for engineering applications: Insights into hydration mechanisms, carbon emissions, and costs
September 2025
Backfilling mining goafs with municipal solid waste incineration fly ash (MSWI FA) and industrial solid waste offers novel possibilities for advancing green mining engineering. However, the recycling...
Synergistic extraction of lithium, rubidium, and cesium from lepidolite: Steam roasting for defluorination and DFT calculation
September 2025
Lepidolites are important carriers of Li ores. Because of the strong positive correlation between the presence of Li and F, Li extracted from lepidolite must be defluorinated. Moreover, synergistically...
CO2 mineralization grouting into fractured gangue voids in post-mining goaf
September 2025
The treatment of post-mining goafs presents a significant challenge for the coal industry, grappling with environmental safety and carbon neutrality goals. To address issues such as abandoned goafs,...
Smart sensors, smart calibration: Applications in machine learning for coal dust monitoring
September 2025
The recent resurgence of pneumoconiosis among coal miners in the United States has been linked to their exposure to excessive levels of coal dust. PDM3700 monitors are used in the mining industry to...
Mechanical properties and damage evolution of rock–backfill composite under impact load
June 2025
The combined failure of rocks and backfills significantly affects the safety of underground mining. Based on the finite difference method (FDM)–discrete element method (DEM) coupled numerical simulation...
