I'm thinking of building a large mobfarm (standard spawn on pressure plates, piston pushes the mob off, dies from fall damage and a waterflow collects the drops).
However, to maximize efficiency I want to build it at bedrock-level (due to lc values), meaning I need to clear out the area that I plan to build this on. Since mobs spawn within 128 blocks, this means I'll need to clear out a 128-radius circle from the collection point, which is a good few million blocks.
I realize the simplist option is to build it in the sky, but due to minecraft's lc value mechanics, the spawn rate will go down significantly and I want it to be as efficient as possible. I've tested with JL2579's mob farm design at bedrock compared to y=180, and the bedrock farm spawned about 2-3x faster.
I don't have any TNT right now (obtaining TNT being the purpose of making a mobfarm), so mining it all out by hand would probably take several weeks. Is there a good mining strategy to clear out large areas, or any better options? It's an SMP server, so no MCedit or world editing. Thanks!

The best would be to build it in stages.
In the end you will have the mob spawner of the size you need.
