 The fracture characteristics of bedded sandstone have a major impact on the safety and stability of in situ coal gasification technology. The study found that the bedding angle has a greater effect on the fracturing process than the sandstone strength. Ultra-weak sandstones are more susceptible to fractures when subjected to certain angles, while stronger sandstones are less likely to break at these angles. Additionally, the bedding angle affects the rate of strength reduction and the ability of the sandstone to resist fracturing. This article was authored by Guoba Wang, Tao Meng, Gan Fong, and others.
