rent a conveyor...
Quick and done...
They use them to unload rail cars...
X2

Tractor trailer would only need unloaded every so many years, why own something and have something 80 feet long the rest of the time in the way and degrading between infrequent uses?

As you have 80 feet from the road to the area where you want to store the coal it would be simpler to purchase 3/4 inch exterior plywood to make a pathway to the storage area where you could just carry it in with a tractor with a loader or a skid loader and just dump it on a concrete pad to store it. So you would need 20+ sheets of 3/4 inch plywood to do this.

Anthracite coal like rock salt, gravel sand or stone sand will attract moisture no matter how much it dries OR WHERE IT IS STORED.

You would need to treat the coal with a sprayed "no cake" solution to keep it from freezing together or wrap the entire bin in pex to keep it warm and the coal free flowing with very hot water and if the coal becomes warm enough it will drip down on the auger and make a big mess.

It would save you much, much more work and aggravation if you decided to pour a slab on grade concrete pad and before you poured the pad lay a very tight spiral of pex pipe and tie wrap it to the mesh and you will be able to heat the coal up and reduce the amount of frozen coal you will have to deal with.

You could use a very small circulator and run it at night on a timer to take advantage of the lower cost of night rate electricity too. You will burn more coal but you will have less much less frozen coal to deal with.

I would be blowing it roughly 80' at a 16° angle into a 22' tall feed bin. thoughts, ideas?

https://www.fbindustriesinc.com/products/transloa ... conveyors/

an un-loader coupled with a basic elevated conveyor should do the trick...
What is the volume of the feed bin...
How much coal do yo use per year...
This would be every 4-6 years...
Double that if it held 50 tons...
These things move product...
easily load 50 ton in less than 30 minutes...
50 ton would be about 2300 cu ft...

CN gonna need this...

Just fill in a road, large stone/rock topped with gravel, back the trailer down in, dump on a pad, and shovel all summer.

Pics we need pics...
LOL...
Yep the low cost method would be to harden the surface...
The synthetic road filter fabric will keep the road solid for years...
But the shoveling up 22 feet...
Split the difference hardened surface forty feet...
Un-loader for the last 40 and 22 foot ascent to the silo...

Again;

1. the exposed storage bin will turn into a popsicle and he will have no coal to burn
a. the coal will still freeze together unless the bin is heated
b. the entire bin could collapse from the weight of the coal
c. mess from B
d. shoveling coal and snow due to b+c
e. frozen coal would not be recoverable until warmer weather
2. the use of the plywood sheets would only be temporary to transfer the coal from the road to storage to make the spouse happy.
4. the storage pad could be poured with a very tight pex spiral to allow for heating the coal pile to help keep it dry as coal will attract moisture
5. purchasing a high quality tarp from FARMTEK will keep the snow and rain out of the coal pile as long as it is secured by weights
6. he stated he only wanted to buy 22 tons at a time in a triaxle load

The bin is 9' Dia x 21' tall. Will hold 15 tons of grain. So I'm figuring I can get a triaxle load into it.
I'm burning about 12 tons a year, so I should get 2 years out of a load

At 40 cubic feet per ton, looks like you could squeeze 33 tons in there if needed...

I worked at a mine where 2 steel bins on the surfaced collapsed for various causes and one of them killed one man and injured the bin operator and the 2nd one collapsed due overweight loading in the bin and almost killed a second man that was standing near it.

Coal of any type will freeze in a storage bin if it is exposed to the elements its a proven fact.

A harvestore silo that has bridged over and caused an uneven unloading has been found to have frozen silage stuck to one side and they have collapsed.

It's a completely enclosed bin, with a hatch on the roof. Top and bottom are cone shaped although the top is more flattish.

no way can i see a 30 ton grain silo for coal. Best a BIG grain silo holds is about 6 tons. Stave silos, concrete design hold a lot of mass. But they are either top feed to unload or bottom feed to unload.Either ones top feed to load harvest in. Always blown in. Design issues...Made for chopped corn/chopped green chop grass. Not rice coal or nut coal.

There are many sizes of grain silos some will hold a couple of hundred tons.
A grain bin may work I had considered one but I worried about it freezing,
I have contemplated on a self unloading forage wagon as a bin.
But at this stage in my life my hand fed bags work nicely for me, I can go pick
up a pallet with the forks on my tractor and bring a ton up to the house stack as many as I wish
to use either the full ton or just half. I only burn a bit over 3 tons a year.
