A two-dimensional model test system for floor failure during automatic roadway formation mining without pillars above confined water
The coal mining in North China is seriously threatened by floor water inrush from the Ordovician limestone, so it is particularly important to explore failure characteristics. Automatic roadway formation mining without pillars (ARFMP) provides an effective method for reducing floor failure. To explo...
