Kuarry is a minecraft mod that adds an upgradable quarry that teleports resources to itself instead of digging a huge hole in the ground, replacing these resources with a placeholder block called "denatured stone". This block drops nothing most of the time, but sometimes you can get gravel from it.
More player testing is needed, but most of things i had in mind are already in.
See github or MCForge forum for more information and screenshots.
The mod depends on Shadowfacts' Forgelin
