井下中深孔回采爆破参数的正交试验优化研究

Optimization study on orthogonal experiment of medium and deep hole blasting parameters in underground stoping

运用正交设计方法进行了井下中深孔回采爆破的优化试验方案设计 ,采用小型水泥砂浆模型进行了模拟试验。经过优化研究 ,得出了适宜于大冶铁矿井下中深孔回采爆破的优化方案。对大孔距技术在井下中深孔回采爆破中的应用进行了尝试。

The orthogonal design method was adopted for optimal experiment scheme design of medium and deep hole blasting in underground stoping, small scaled cement mortar model was used for the simulation experiment.Through optimization study, the optimal scheme suitable for the underground medium and deep hole blasting of Daye iron mine was worked out, and the application of large hole space blastingte technique in underground medium and deep hole blasting has been made.
