Question about Thor's fighting style.

If no one in the universe, not even the hulk, can pick up Thor's hammer when it is left on the ground, why not use that fact for a tactical advantage? Why not, if there is a monstrously gigantic villain, do they not knock him to the ground and then just place the hammer on top of him while they knock him senseless?

Then what?

Is the chest of the star-consumer beast of ak'thraben to be the resting place of Mjolnir for all eternity?  And what might He Who Laughs Thunder use to crush the spines of OTHER adversaries in the meantime?

Not to mention, a vast majority of Almighty Thor's epic battles happen in the air, or space, or some other such place.  And even upon the ground - Mjolnir may be indestructible and unmovable, but the ground is hardly so!  Many a foe could simply tunnel downward to escape this childish "trap."  While none but Glorious Thor Thundergod can move Mjolnir once placed, it does not create infinite downward force - otherwise, during the Thunder God's battle with the Hulk upon the S.H.I.E.L.D. helicarrier, The Hammer of The Gods would have broken through the hull and plummeted to (the center of) the Earth as soon as the Bringer of Storms put it down!
