Numerical modeling of entry position design: A field case
In coal mining, roof collapse and support body failure during entry excavation are a common problem. During excavation, entry positions may be subjected to separation, shear-slip, support body failure, and roof collapse. Weak coal-rock interfaces allow for shear-slip between layers, causing anchor b...
