Latest Patents

One of Peihua Zhang's key patents is titled "Method for ecological filling with mixed coal gangue and fly ash." This patent outlines a comprehensive approach that includes several steps. The first step involves the construction of a double-impermeable base layer, which includes leveling a pit or gully, laying a fly ash-based cementitious material, compacting, and curing. A polymer waterproof coating is then sprayed on the surface of the cementitious material, followed by full curing to create a protective structure. The second step is three-dimensional layered filling, where coal gangue and fly ash are dumped in sequence on the protective structure. The coal gangue, which is processed after coal washing, serves as an aggregate, while the fly ash acts as a filler and cementitious material to achieve a compact filling structure. The final step involves rolling the layered filling with a roller to ensure stability.
