We are aware that the stress around a borehole blasting are dependent on the blast loading rate , i was doubtful if PPV is affected by the loading rate?
Yes, PPV is depend on the quantity of explosive blast in one time. If you blast huge quantity of explosive the PPV will be increases and minimize with distance.
Yes, that is definite thing and is accounted in the very scaled distance, i am asking about the loading rate lets say using the same amount of weight of explosive.
All right, after concerning with my mentor I confirm that PPV is not affected by loading rate either you pour into bore hole at slow rate or fast rate.
Loading rate is totally related with density of explosive and PPV is not much affected by density.
