Optimization of the matching relationship between the stemming length and minimum burden in cut blasting of large-diameter long-hole stopes
Abstract Cut blasting, in which new surfaces and relief space for subsequent blasting Home are created, is one of the most critical steps in the establishment of large-diameter long-hole (LDL) stopes.To reduce the damage to the chamber roof caused by stemming recoil and improve the rock breaking effect, 15 groups of small-scale model tests with min
