I have a few strategies for stone management (and I do large-scale mass dumps).
- As much as possible, I run only a single quantum stockpile at any point. And it's only 2-3 tiles away from my main staircase, and either at the very top or bottom of the fortress. Usually at the bottom of the main stairs because that puts any scooped up raw ore closer to the magma smelters.
- Keep your mason workshops, stonecraft workshops and mechanic workshops *far* away from the location of the stockpile. If the stockpile is too close, then you'll have them grabbing stone from the dump pile after you do a d-b-c reclaim. So my workshops tend to be at the top with the quantum stockpile at the bottom of the overall design.
- Right outside my mason, stonecraft and mechanic shops, I create small 2x3 and 3x3 stockpiles of the types of stone that I want to be used for those crafts. I keep these workshops away from the other types as well. Since the workshops are 10-20 tiles away from the quantum dump zone, the workers will pull from the smaller stone stockpiles right outside the shops. If I have 3 mason shops in a row, I'll have 3-5 small stockpiles feeding them (total of 15-30 tiles total). Those are basically my only permanent non-economic stone stockpiles. The stone haulers keep them filled, and the mechanics / masons / stonecrafters only walk a few tiles to fetch stone to make stuff.
- If I'm getting ready to do large-scale wall / floor building, I will create temporary stockpiles of up to 50 tiles worth of the desired stone type. Once the stockpile fills up, I'll start construction. Even for smaller construction projects, small 3x3 or 3x5 stockpiles let the masons construct walls / floors faster.
- Down by the smelters, I will create narrow 1x11 strips of the various ore types (Limonite, Magnetite, Tetra, Native Gold, etc.). Again, the stone haulers will keep them filled and my furnace operators won't go wandering all over the fortress (or 50+ tiles back up from the magma) to get raw materials. Don't forget a 3x11 stone stockpile that takes the 5 flux stone if you're doing steel.
If the fort is compact (keep within a 40x40x40 cube, don't sprawl) and the quantum dump is in the middle then it doesn't take all that long to clear the entire fort of loose rock / ore. With nothing more then 15-18 tiles away from the main stairs, moving things around goes *fast* and my stone / refuse haulers end up idle a lot by the 2nd/3rd year.
