摘要
通过对无底柱崩落法爆破边界条件的分析，提出了一种经济可行的回采炮孔布置方式，并在白银公司深部铜矿的炮孔施工中获得成功。
Based upon the random medium caving theory and experimental data,this paper analyzes three boundary conditions respectively.An economical and feasible layout of blasting bores is put forward in using sublevel caving method.It is used success.fully in Bai Yin Copper Mine.
