Mining ore conveyor is misbuilt and near unusable.

[PenguinsMeep]

The ore conveyor that goes form the space arc smelter/magnets to the mining equipment room is nearly unusable due to the lack of a airlock. The decompression wind caused by opening the conveyor door is much more powerful than the conveyor, resulting in the crate being stuck outside until all the air is drained from the mining equipment room. A airlock should be built to make this conveyor of any use.

this should be done I agree, this was like going to QM only to realize there's no oxygen because someone forced the conveyor doors open and left them that way.
