露天矿邻邦控制爆破的研究

本文对控制爆破中的光面爆破、预裂爆破、药室抛掷爆破和邻近边坡的控制爆破技术进行研究,分析其破坏机理和确定爆破参数。对后一种控制爆破技术结合不同的地质条件,对邻近边坡炮孔采用不超深,不堵塞空气垫层及在软岩中打短炮孔的方法,达到保护边坡的效果。

Investigation of Control Blasting Near Slope in Open pits

This article investigates smooth blasting,pre-splitting blasting, explosive room casting blasting and near slope control blasting technology, analyses their fractur mechanism and confirms explosive parameters For the last control blasting technology, considering different geological conditions, use no overdeepness,no packing,air cushion and short explosive hole to protect slope.
