摘要
对最大高差 43.47m、长约 45 0m、宽约 180m的矿体实施爆破 ,因地质条件复杂 ,设计采用了 2层 6排条形药包、总装药量 35 0t、排间及排内微差起爆的硐室大爆破。介绍了该工程爆破的药包布置、爆破参数。
The ore body with maxium height difference of 43.47m, length～450m and width～180m was exploded . Due to its complicated geological conditions , a chamber blasting with 2 layer-6 row stripped cartridge , total charging 350t and millisecond detonation between rows and inner rows was designed and adopted. The cartridge layout, blasting parameters, time difference in detonation and blasting effectiveness are introduced .
