You're going to have that to some degree no matter what, the pieces in the middle are more likely to be flat too. Remember coal can flow like cement down the chute, if possible for the next delivery ask the delivery person to just dribble it into the bin. You can slow it down to a crawl as long as you have the right pitch and whether that is possible depends on your circumstances. Even if it has a really high pitch you can slow it down with a broom basically causing a back up but don't try and do this yourself because if the chute gets overloaded at the very least you'll have a big mess... at worse it will crumble and that's $$$.
Remember one thing... don't touch the coalman's chutes unless he asks you too. They are very expensive, that was always my one pet peeve people trying to "help" me and causing some major damages to the chutes. A ding to you might mean nothing, to the coalman it means there is going to be a hole in it shortly making it useless.
