When I used bagged coal, and it was really wet, I would clip a single corner of several bags ahead of time approximately 3/4" diagonally and stand the bags on that corner in a plastic tray to drain. A grid or make shift lattice affair in bottom of tray will help too. It was convenient for me that I had a floor drain right there and I had a hole in the tray letting the water run down the drain.
What little water/moisture remained in the bags was never a problem and dust was still under control. This is one case where Gravity is your friend.
No need of a shovel for this method.
I found that this took minimal effort on my part to get satisfactory results.
