Is there a name for this checkmate?

What's interesting about this checkmate is that there are seven black pieces and five black pawns guarding the escape squares of the white king. Only the rooks, a few pawns, and the black king are not involved in guarding the escape squares of the white king.

which checkmate?

i did this by navigating to the position in the analysis window and then i copied the link from the adressbar. Regarding the checkmate, i dont think it has a name.
