Parameter optimization of the slope pre-splitting blasting

XU Ming-biao PENG De-hong(1.School of Civil Resources and Environmental,Wuhan University of Technology,Wuhan 430070,Hubei,China 2.Department of Civil Engineering,Yiwu Industrial and Commercial College,Yiwu 322000,Zhejiang,China)  
Pre-splitting blasting is often used in slope engineering construction,pre-splitting parame- ters have important effects on reducing blasting vibrations.Pre-splitting blasting experiments were carried out to obtain normal pre-splitting blasting parameters such as hole diameter,hole space,gun- powder charge line density,and uncoupling factor.Ideal pre-splitting blasting parameters for four dif- ferent hole diameters gained by the code ANSYS/LS-DYNA agree with the blasting experiments.By regression analysis,a simple fomula was given to choose the pre-splitting blasting parameters and to guide the suecedent construction.Practice shows that combination of blasting experiments and numer- ical simulations is helpful to optimize pre-splitting blasting parameters.
