A physical model is created to describe stage-by-stage fracture of rock mass by deep-hole blasting. The analytical dependences are presented for main parameters of massive blasting. The zones of intense and passive crushing are identified in a blasted bench. The formulas are obtained to calculate volumes of different size particles in these zones. The automated determination procedure of particle size distribution is proposed. The program in Microsoft Visual Studio 2017 environment allows the automated analysis of blasthole pattern in a bench and particle size distribution in broken rock mass depending on initial data.

台式爆破破碎破碎岩石的粒度组成生成

创建物理模型来描述深孔爆破岩体的逐级破裂。给出了大规模爆破的主要参数的分析相关性。强烈和被动破碎的区域在爆破台上确定。获得公式来计算这些区域中不同尺寸颗粒的体积。提出了粒度分布的自动测定程序。Microsoft Visual Studio 2017 环境中的程序允许根据初始数据自动分析工作台中的爆破孔模式和破碎岩体中的粒度分布。
