Making use of multi-well method, the quantity of rock salt mining is more, the concentration of brine is higher, and the shape of cavity is regularer than others.
The cut is major factor to affect tunnel blast. The movement process of rock pieces in cut cavity is a theory base for cut blast mechanism and the parameter design.
