Land mine and remote mine spells

Land mine and remote mine spells

Ok if any of you have played DOTA you know about the landmine and like remote mine ability that the golbin technies have

first off How in the heck do you do both of those spells, expecially the remote mine one,

I have no clue how to plz HELP?

thx

I've played DotA,but I don't know either of those spells. Oh, wait, you probably play that fake version, DotA Allstars. Well, I've played that, but I've never been the goblin, so you'll have to describe those two.
I will say, however, that I'm pretty sure that the regular mine skill just summons a mine.
