I've mentioned this in another thread, but I think it's legit enough to put here too:
I think it'd be awesome if there could be a tactical structure that could auto-deploy mines to a specified location for you. This structure would also have the capability of slowly replacing "used" exploded mines autonomously, but each of these structures could only maintain a certain number of mines. (10, 50, 100, whatever balances the best).
This makes mines less of a micro-management thing as well as the whole "OMG 1000s of mines" kinda thing that also take forever to clear and seem to bog down a lot of computers graphically.
I agree with this and in fact had a similar post a while back:

See reply#29.
Some type of limit has to be put on mine deployment to prevent the computer from spamming them and to prevent the game from lagging.
As I said in another thread, allowing players to turn on/off mine deployment (like we can pirates) when setting up a game is a must. In larger longer games the mines make it a tedious chore to advance, and slow the game speed down a lot. (processing speed I mean, not just playing pace)
I feel that this is also doable without interfering with game balance. Besides, I feel that when it comes to space, any mine aside from homing mines is just plain unrealistic. Even when placed in orbit around a planet, the distance would just be too great to hope that someone would happen to blunder into a drifting mine field (also in the post mentioned above).
As far as clearing the mines out, I played a game a while back where the minelayer also had the equipment to detect and remove mines as well. You just had to select the "clear mines" function and it would automatically clear the area selected (and it used a laser to do this, which just plain looked cool). Another option could be to have a ship equipped with a weapon with a large area of effect (which could be equipped by default or reasearched), such as a missile with a large fragmentation warhead that would send out large numbers of fragments to impact and detonate mines over a decent-sized area. Or you could do some research that allowed you to upgrade your scouts into minesweepers, arming them with not just the ability to detect mines, but with one of the above mentioned weapons. Not only does this keep players from discarding their scouts later in the game, but it also makes them MORE valuable. Also, having the scouts with the ability to detect AND remove mines decreases micromanagement since they could be set on "auto explore".
