Article Synopsis
- Researchers collected coal samples from the Yuwu mine in Shanxi Province to study how acid treatment affects their pore structure and gas permeability.
- Hydrochloric acid (HCl) at a 10% concentration was used, showing that acid treatment decreases micropore volume while increasing mesopore and macropore volumes, resulting in smoother coal surfaces.
- The study concluded that after 30 hours of treatment, coal permeability can increase by about 9.43 times and reaches a stable state regarding total pore volume and fractal dimension, suggesting that 30 hours is the optimal treatment duration.
