摘要(Abstract):

在模型被爆体性质、几何参数和爆破动力相似性研究的基础上 ,对井下中深孔爆破的四种方案进行了模拟 ,得出了较优的方案。现场试验得到了与实验室试验同样的结果 ,这说明模拟试验是成功的 ,为井下中深孔爆破参数的优化研究工作提供了极大的便利
On basis of studying the similarities in properties, geometric parameters and blasting dynamics of the body to be blasted in a model, the simulation of four schemes of underground medium length hole blasting are carried out and an optimal scheme is given A same result as the experiment has been obtained in a field test It indicates that the simulation experiments are successful and facilitate the optimization of the parameters of underground medium length hole blasting
