摘要
根据程家沟铁矿临近边坡生产爆破的生产实践，提出了适合于该矿的露天矿临近边坡预裂爆破的装药量、微差间隔时间等爆破参数的确定方法，并对其实际应用情况效果进行了分析。
In demand of the production practice of side slope of production-blasting in Cheng Jiagou Iron Mine,this paper proposes a method to decide the blasting parameter of powdered charge and millsecond internal-time which fit open cast mine to blast nearby side slope and analyze the practial effect.
