In this article, the atmospheric pollutants carbonyl sulfide (COS) and HCl in blast furnace gas are taken as research object. Catalysts with γ‐Al 2 O 3 carrier alkaline metal oxides active components prepared for synergistic desulfurization chlorine resistance of gas. The results show that CaO–ZrO /γ‐Al hydrolysis catalyst has best performance. removal rate COS is maintained at more than 95 wt%, maximum can reach 99 overflow H S also 80%. At same time, treatment efficiency about 90%. This work provides an effective reference acidic harmful actual industrial

To expedite the achievement of ''30-60 double carbon'' goal, it is imperative to create a novel, low-carbon, cost-effective, and sustainable backfill material for mining purposes. Against this background, paper investigates workability, carbonation performance carbon sequestration capacity coal gangue (CG), magnesium slag (MS) fly ash (FA) as solid waste material. The results study show that: (1) rheological properties CFM fresh slurry conform Herschel-Balkley (H-B) model, its flowability meets requirements mine transport. With increasing MS content, yield stress, apparent viscosity, thixotropy shear thickening increase, micro-slump diffusion diameter decrease. (2) Carbonation curing can effectively improve early UCS CFM. highest was 8.854 MPa after 7 days curing, which 27.84 times higher than that standard curing. In addition, increased with increase age content. (3) produces large number products such calcium carbonate makes microstructure denser. (4) absorb up 14.55% CO2 carbonation. (5) volume stability significantly improved summary, not only new type low-cost, low-carbon material, but practical application in field backfilling also has great potential realisation resource utilisation sequestration.

Water-soluble mining was invariably associated with surface subsidence, which in some cases escalated to the movement, deformation, and even collapse of overlying rock layers, triggering grave subsidence calamities. The caprock salt-bearing strata Longgui salt area closely adjacent third aquifer, mainly consisted fractured, porous, high-permeability materials such as mudstone conglomerates, rendering geological conditions highly complex. Years water-soluble had led significant area, a trend toward accelerated subsidence. In this study, were analyzed, through simulated experiments pillar dissolution mining, mechanisms examined. Over time, gradually perforated pillars caprock, ceasing support ultimately transforming small cavities into large single cavity. Utilizing data, research employed numerical simulation inverse predict patterns from 2019 2025, revealing that maximum reached 1367.6 mm I 1879.5 II, rates 12.05 mm/y 44.78 mm/y, respectively. Moreover, impact ground on construction subways assessed by establishing monitoring points evaluating along subway cross-sections longitudinal directions. findings provided valuable insights for guiding prevention control calamities mine similar areas Guangzhou, China.
