Transporting The Coal from The Face of The Shaft
From an article on British Coalmines

    With early drift ( i.e. tunnel ) mines, coal was loaded into baskets or boxes, which were either carried or pulled along the floor. A small drift mine in Shropshire (the Foxhills footridge) was still using a wooden box, pulled manually by a length of rope, in this way as recently as 1915. There is some evidence of the early use of wheelbarrows in coal mines, too. Baskets  made from plaited hazel wands were used in most coalfields until well into the nineteenth century. In the Scottish stair pits, women carried the coal in baskets on their backs along the underground tunnels and up ladders to the pit top as recently as the 1840s. 

In the East Midlands, donkeys driven by young boys were employed at this period to draw the corves to the main roadways, where they were loaded on to wheeled carriages (called trams) which ran on rails to the pit bottom. The ass-lad had to control the movement of the corf with a leather dog-belt which he wore round his hips and which was attached to the corf by a chain and hook. Where the roadways were too low for donkeys, children drew the corves (or in some cases wheeled trams) with the dog-belt, either on hands and knees or bent double. For example, this was fairly common in West Yorkshire, where both boys and girls were employed. 

Sometimes a rope harness, called a guss, was used instead of a dog-belt, and this device was still used at a few Somerset collieries in 1947. In Northumberland and Durham the corves were drawn on sledges to the main roadways by boys, then loaded by a crane on to long wheeled carriages (rallies), running on rails. Rails, first introduced underground about 1760, were laid only on the main roads until after the change in shaft technology which took place about 1840.
