%X Based on the characteristics of hole-charged blasting, the mechanism of action, the stressing and the movement of the stemming material are analyzed according to the blasting theory and the stress wave theory, and the expression of the length of the stemming material is deduced. On the basis of theoretical derivation and analysis, the experiment of stemming and its effect on blasting results was carried out. The experimental results show that the stemming in hole-charge is important and necessary. It may serve as a theoretical basis in the parameter design of blasting.
