If you #untrap an activated land mine trap, it will turn (back) into the land mine item.
Activated land mines are only randomly generated at dungeon level 6 or lower. There are also many in the treasure room in Fort Ludios.

Effects
Trying to set a land mine while fumbling, or setting a cursed landmine has a chance of detonating it instead. The chance is modified by Luck; if your Luck is maxed, the chances are very slim. Setting a land mine while riding a steed with Unskilled in Riding has the same chance of failure, and an even worse chance if also fumbling or using a cursed landmine, also causing it to detonate.
Land mines explode when triggered, which will do 1-16 damage, wound your legs and leave behind a pit. You may untrap a land mine from an adjacent square, and then pick it up and install it elsewhere, similar to a bear trap.
Monsters have only a 1 in 3 chance of setting off a land mine when they step on one.[1] Flying creatures are even less likely to set one off (and won't ever fall in the resulting pit), although there is still a slim chance that air currents will activate the mine.[2]  Land mines can also be set off by rolling boulders.
Any items on the same square as an active land mine will be blasted around the room (or destroyed, if fragile) when it goes off.
A land mine that is triggered adjacent to a body of water like a pool or moat will create a pit that immediately fills with water, likely immersing you in the process.

Strategy
Be careful, as you can set off your own land mines if you move on to that square or fail to untrap them. Ensure your land mine isn't cursed, you aren't fumbling, and you aren't riding.
Since some monsters tend to pick up items left lying around, you might be able to lure victims on to your land mines with bait that appeals to them.

Mine fields
Because monsters can often get past them, placing a single land mine is usually not that effective.  However, you can set several mines to make a mine field, which might be handy for dealing with certain special rooms filled with monsters.  You could also use a mine field to protect the area around a stash. It can also be used as a warning system to alert you to the presence of monsters: "Kaablamm!  You hear an explosion in the distance!"

In SLASH'EM, you can also recover a few more from  Grund's Stronghold, assuming the monsters there don't set them off.
