分析矿床地质 提高爆破效果

在复杂地质条件下，通常的台阶爆破爆破效果差，飞石危害大。针对金牛山石灰石矿区的复杂地质条件，采用了提高爆破效果的一系列技术措施。实践证明，采用减小炮孔参数，改变装药结构，变化起爆顺序等方法，均可提高爆破效果；采用适当的压渣爆破，根据季节适当调整爆破规模等可有效控制飞石危害。

Analysing geology of mineral deposits to improve blasting effect

In complicated geology of mineral deposits, blasting effect is not satified while using normal bench blasting, and fly-stone harm is also large. Aiming at complicated geology of Jinniu mountain mineral, a series of technical measures are adopted to inprove blasting effect. Practice shows that adopting methods such as decreasing boring parameter, changing structure of explosive setting and sequence of initiation,etc. can improve blasting effect; Adopting proper compression blasting, adjusting blasting scale according seasons, etc. can effectively control fly-stone harm .
