深孔台阶爆破飞散物预测公式的分析与修正

Correction and analysis of the predictor formula about deep hole blasting flying rock’s casting distance

本文利用三峡工程永久性船闸深孔台阶爆破飞散物的相关数据,对多个深孔台阶爆破飞散物的经验公式进行工程实例回归分析比较,从而得到在深孔台阶松动爆破较精确的飞散物公式,进一步通过数据拟合的方法,对其进行修正,提高飞散物预测的精度。

In this paper,through regression analysis and comparison of empirical formulas for the flying rocks in deep-hole bench blasting based on the data of the Three Gorges permanent lock,a more accurate formula of flying rocks in deep-hole bench loose blasting was obtained.Then the formula was revised and the accuracy of flying rocks prediction was improved by fitting method.
