Admin Commands for Mining?

I'm trying to make a completely flat surface across an entire planet. I was wondering if there's an admin command to help mine faster.

 

/spawnitem superfishaxe 1

 

Cool thanks! I've actually managed to do all the mining by hand, but I'll keep this in mind for later

 

And if you want one that gives you the drops too, use

/spawnitem superfishaxedrop 1

 

thanks! this is making mining WAY easier. ^-^
