井下高台阶柱状药包爆破技术及其应用

THE APPLICATION OF BLASTING TECHNOLOGYWITH HIGH BENCH COLUMN POWDERPACKAGE IN UNDERGROUND

论述了井下高台阶柱状药包爆破技术的实质，即利用侧向和下向两个乃至多个自由面进行爆破回采的工艺技术。是露天大孔台阶爆破技术在井下开采中的应用。通过对井下高台阶柱状药包爆破机理的初步探讨和理论分析、计算，为露天台阶爆破井下化提供了依据和参考。

Discoursing upon the essence of blasting technology wity high bench column powder package in underground, and makinguse of sideward、downward and even multiple free face to carry on blasting and mining technology,is the application of open - pit large hole bench blast technique in underground mining. Through the initial inquring、theory analyzing and calculating the blasting mechanism of high bench column powder package in underground,be provided basis and reference for the undergrondize with open - pit bench blasting.
