Research on mechanism and risk assessment of water and sand outburst in weakly cemented rock layers of Jurassic coalfields

Due to the relatively late coal-forming period in the Jurassic coalfields in western China, the rock characteristics often exhibit poor cementation, low strength, and easy softening and collapse in contact with water, which leads to the occurrence of water and sand outburst events in weakly cemented...
