摘　　要：以南炼厂保安矿柱上分层矿体一期工程开采为例,介绍了其相关参数的确定、测试分析与校核。通过现场爆震测试检验,一期工程开采选用的爆破参数保证了南炼厂地表建(构)筑物的安全,爆破引起地表建(构)筑物产生的震动参数低于国家《爆破安全规程》给出的允许值。可作为后期南炼厂保安矿柱上分层矿体或类似条件矿体开采的爆破设计与施工的参考依据。Taking the first engineering of mining the upper ore of the protecting pillar under the south smeltery as example, the paper introduces the determination of relational blasting parameters, the blasting vibration testing and checking. The in - situ test of blasting vibration indicated that the selected blasting parameters for the first engineering of mining the upper protecting pillar ensured the safety of the surface buildings （structures） in south smeltery, the velocity of particles vibration induced by an explosion on the surface buildings （structures） was lower than the limiting value presented in the ＂ Safety Regulation for Blas- ting＂ （ GB67222003 ） , so the determined blasting parameters can de used as the reference to blasting design of mining the upper ore of the protecting pillar under the south smeltery as well as other resemble orebody.
