on july 23, chn energy's national institute for clean-and-low-carbon energy (“nice” for short) successfully completed an underground ton-level application test of its independently developed inorganic composite grouting reinforcement material. the material was successfully used for pre-injection reinforcement of fractured coal and rock in the mine's roadway.
the inorganic composite grouting reinforcement material offers several advantages, including inherent safety due to a non-exothermic hardening process, excellent mechanical properties, ease of use, no odor, and low-carbon footprint. this material provides coal mining companies with a superior choice for grouting reinforcement, improving safety, reducing costs, and effectively utilizing solid waste such as fly ash.
