Study on a Quantitative Evaluation Method of Goaf Instability Risk of Phosphate Deposits in Layered Rock Mass

Study on a Quantitative Evaluation Method of Goaf Instability Risk of Phosphate Deposits in Layered Rock Mass

Goaf instability accidents such as roof falling, rib spalling, or pillar spalling often occur during the room-pillar mining process in layered phosphate deposits, severely affecting mine production safety. Considering that the spatial variability of rock mass mechanical parameters is rarely incorpor...
