I'd like to know how to get my mining pipe out of the ground.

put batery in bottom slot and in upper one any block which you like to fill mining hole and mining pipes will be stored in chest nearby

The Miner will then start WITHDRAWING all laid Mining Pipes and replace them with the filling material (of the upper slot).
