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 stage of stratified ore body mining on the security pillar of South refinery as an example, the determination, testing, analysis and checking of the related parameters are introduced. Through on-site detonation test and inspection, the blasting parameters used in the first-stage mining project ensure the safety of the building (structure) on the surface of the South refinery. The vibration parameters caused by blasting on the surface are lower than the national blast safety regulations "Given the allowable value. It can be used as a reference for the design and construction of blasting for the mining of layered orebodies or similar conditions on the security pillars of the late refinery.
