AI Technical Summary
Existing coal mine gangue processing methods are inefficient and have low gangue content, making it difficult to meet the needs of long-distance pumping and goaf diffusion, thus limiting the development of coal mines.
A fluidized filling slurry preparation method using large-particle-size gangue was adopted. By adjusting the mass ratio of gangue, cement, admixtures and water, the finished gangue particle size was prepared to be 0mm-1mm and 1mm-3mm. Magnesium aluminum silicate was used as an admixture. The mixture was stirred to form a slurry, which improved the gangue content and fluidity.
It improves the gangue processing capacity, meets the requirements of long-distance pumping and goaf diffusion, enhances the fluidity and diffusion performance of the slurry, and improves the gangue processing efficiency.
