Highwall mining is an adaptation of auger mining. Instead of an auger hole, an entry into the coal seam is made by a continuous miner, remotely operated from a cabin at the surface. The cut coal is transported by conveyors behind the miner to the outside. Using a television camera, the operator can see and control the miner's progress.
Everything changed during the Industrial Revolution, which began around 1750. People found an extra source of energy with an incredible capacity for work. That source was fossil fuels — coal, oil, and natural gas, though coal led the way — formed underground from the remains of plants and animals from much earlier geologic times.

Big Muskie. Big Muskie was a legend among machines while in operation. Also called Muskie and Ol Musky, the machine was a model 4250W BucryusErie dragline. It was the only model ever built, and took two years and some 200,000 hours to construct. When Muskie was built in 1969, it cost 25 million dollars. That's approximately 171 million today!
The first of these fossil fuels used by humans to generate energy was coal. Coal was the first and the only fossil fuel to be used until the 1860s when the use of crude oil began.

Newcomen's atmospheric steam engine. The first practical mechanical steam engine was introduced by Thomas Newcomen in 1712. Newcomen apparently conceived his machine independently of Savery, but as the latter had taken out a wideranging patent, Newcomen and his associates were obliged to come to an arrangement with him, marketing the engine until 1733 under a joint patent.

Step 5: Finish the Striking End and Add a Touchmark/Maker's Mark. I forged the striking end into a hexagonal shape, also for looks. The last step of forging is to stamp it as a signature. My touchmark is a simple, Runic "T". Stamping it will slightly distort it, so make sure to straighten the workpiece again.
