Abstract
In the cause ofdecrease the bulk rate and dilution rate of ore,the influence of three horizontal factors of hole depth,side hole angle and fan-shaped hole row inclination angle on the bulk rate and dilution rate of ore was studied by orthogonal test and range analysis.Practice has proved that the orthogonal test is used to optimize the blasting parameters,which effectively improves the underground blasting effect and improves the production efficiency.For the bulk rate and dilution rate index,the inclination angle of the fan-shaped hole row surface is the most significant factor.Taking an iron mine as an example,the optimal blasting parameters are obtained by optimization.The hole depth is 16m,the side hole angle is 55°,and the inclination angle of the fan-shaped hole row is 90°.It has certain reference significance for further controlling the block rate and dilution rate of underground mines.关键词
