| 摘 要： | 为了分析不同空腔条形药包爆破效果,以动光弹为研究手段,用五种不同空腔比实验模型进行了爆破动应力场及破坏结果研究,并在首钢128t硐室大爆破中进行了工程应用.研究和应用结果表明:最佳空腔比约为4.0;在岩石特别破碎地区为控制飞石,可采用大空腔比进行爆破设计理论.

| Abstract: | In order to analyze the blasting effect of linear charge at different cavity ratios, the changes of stress field and the destroyed effect at five cavity ratios were investigated by dynamic photoelasticity in experimental models. These were applied to 128 t chamber blasting in Shougang Mine in China. The results indicated that the cavity ratio above 4.0 was suitable. And a bigger cavity ratio in a broken stone area was designed for controlling fly rock. |

| Keywords: | chamber blasting cavity ratio blasting effect linear charge dynamic photoelasticity |
