Let's consider the Springer resolution of the nilpotent cone $\mathcal{N}$ of a complex semisimple Lie algebra $\mathfrak{g}$, which is $$ \widetilde{\mathcal{N}}=T^*\mathcal{B}\rightarrow \mathcal{N}. $$ It is a resolution of singularity of $\mathcal{N}$. ( For the construction of Springer resolution you can see section 6 of "Geometric Methods in Representation Theory of Hecke Algebras and Quantum Groups" .)

My question is: is it a blow-up along some subscheme of $\mathcal{N}$?

Or for the simplest case, where $\mathfrak{g}=sl(2,\mathbb{C})$. Now $$ \mathcal{N}= \{x^2=yz\} \in \mathbb{C}^3 $$ In this case is $\widetilde{\mathcal{N}}$ the same as the blow-up at $0$?
