摘　　要：根据露天台阶爆破模型模拟试验的相似律 ,制作模拟宜阳矿生产现场的小型水泥砂浆模型 ,进行原型方案和改进方案的爆破模型比较试验 ,并对可能产生的失真以及弥补方法进行探讨。两个典型试验结果表明改进方案好于原方案 ,爆破优化模型提供的改进方案是可行的 。According to the similarity law of simulation test about open step bench blasting models, the small concrete model for the production spot simulation of Yiyang Mine is made, the primary scheme and the improved one is compared by model test and the possible distortion and the remedy are described The two typical test results show that the improved solution is better than the primary one The improved solution obtained from the optimized blasting model for Yiyang Mine is applicable, and on this basis industrial test can go on at Yiyang Mine
