Trenchless 11 Block Quarry

by Kades and SPB11 An overworld 11 block quarry which does not require clearance on the bottom or sides. Features: - Can mine every block above bedrock - Uses 3-way return stations. This decreases build effort significantly, but increases lag - Cartless, coralless dupers - Speed: 8m 23s per 88h slice - 98% collection rate (1.17+) - Non directional, non rotational Preparation: - 24m main trench - Requires a shield to block water from flowing in from the sides, or a 1m side trench. Lava does not need to be shielded - Does not require a bottom trench - Adjust height by changing the distance between the top and bottom sections in 11m increments - Width is adjustable in 18m increments - Minimum height: 66m | Minimum width: 48m - The gravel remover part is optional. If you build it you will have to manually push down or remove the blocks which get left in its way when the quarry first launches Note: this quarry has several failure modes which can occur very rarely.
