摘要
在露天矿中深孔爆破生产实践中,对岩体可爆性的判断是选择爆破技术参数的重要依据,这种判断的准确性,最终决定着实际爆破效果与预期效果之间的一致性。分析并确定影响岩体可爆性的各种因素,同时建立一种对岩体可爆性进行定量描述的有效方法,在此基础上建立岩体可爆性分级数学模型,并在本钢歪头山铁矿得到了应用。
In the long-hole blasting practice in open-pit mines, the judgment of rock blastability is an important basis for choosing the technical parameters of blasting. The accuracy of such judgment finally decides the conformity of the actual blasting effect to the predicted effect. The factors influencing the rock blastability were determined and analyzed and an effective method was established for qualitative description of rock blastability. On this basis, a mathematical model for rock blastability classification was built and applied in Ben Steel＇s Weitoushan Iron Mine.
