Are the natural deduction introduction and elimination rules for the universal and existential quantifiers in Intuitionistic Logic the same as those for Classical Logic?

Yes, they are.

See Intuitionistic Logic.

In terms of "standard" natural deduction rules, the only rule rejected by Intuitionistic Lofic is RAA rule (or Double Negation, equivalent to LEM - see this post).
