| Abstract: | In the paper,the influences of parameters such as the density of line charge,aperture,and pitch,etc.on presplit blasting,as well as the correlations among them are studied by comparative analysis of small-aperture presplit blasting test and normal production of presplit blasting by side slope.Finally,the blasting patterns and reasonable parameters suitable for by side slope of Baiyunebo Iron Mine are found out. |
