摘要
抛掷爆破爆堆的形态对于倒堆系统总作业量与成本、后续倒堆环节的工作面参数设计工作等有着至关重要的影响,针对当前爆堆形态样本量不足、错误数据影响预测效果等问题,提出了爆堆形态的标准化分析-处理方法,具体包括数据库的构建、基于工作面形态特征的样本筛选及分类、基于爆堆形态特征的样本筛选与分类,实现了海量爆堆数据的快速处理,提高了样本的有效性。利用局部加权线性回归对样本集合进行回归分析,最终获得了三组具有普遍解释意义的典型爆堆曲线,研究提出的处理方法具有快速、高效、便捷等特点,为现场抛掷爆破-拉斗铲倒堆工艺的设计提供了准确的依据。
The shape of throw-blasting has an important influence on the total work quantity and cost of the stacking system,the parameter of the work-face design of the subsequent casting link,etc.Aiming at the current problems of insufficient sample size of the muck-pile shape and of the influence of incorrect data on the prediction effect,a standardized analysis and treatment method of muck-pile shape is put forward.The method includes the construction of muck-pile’s database,the selection and classification of the work-face shape characteristics,and the selection and classification of the muck-pile shape characteristics.It realizes the fast processing of massive muck-pile shape data.And it improves the effectiveness of samples.Finally,three groups of typical muck-pile shape curves with general interpretation significance are obtained by LOWESS.The methods are fast,efficient and convenient,which provides an accurate basis for the design of the technology of throwing blasting and dragline casting in the open-mining.
