   Excavators
   

Miners traditionally used shovels and steam shovels to break and remove earth, but today’s miners rely on excavators. An excavator is a mobile vehicle that moves on tracks or with standard wheels. It features a rotating platform, off of which comes a hinged arm with a bucket or scoop attached to its end for digging.

2. 
   Draglines
   

A large excavator with a bucket pulled in by a wire cable. Draglines are enormous earth moving machines that miners use to drag away dirt and expose underlying coal or mineral deposits. Draglines are some of the largest machines on the planet, and can remove several hundred tons of material in a single pass.

3. 
   Drills
   

Miners who extract natural gas and oil commonly rely on drills to reach underground deposits before piping the resources to the surface. Coal and mineral miners also use drills to create extensive series of holes, which they then fill with explosive charges to blast away chunks of earth.

4. 
   Roof Bolters
   

Roof bolters are large, hydraulically-powered machines used to force bolts into roofs. Miners use roof bolters to support tunnel roofs and prevent underground collapses.

5. 
   Continuous Miners
   

Continuous miners are machines with massive, rotating arrays of teeth, often made from tungsten carbide. Subterranean coal miners use the machines to scrape coal from coal beds. In particularly dangerous situations, workers control robotic continuous miners remotely.

6. 
   Longwall Miners
   

Longwall Miners - massive shearers cut coal from a wall face, In contrast to continuous miners, longwall miners remove large, rectangular sections of coal instead of scraping coal from a bed bit-by-bit. According to Kentucky Coal Education, continuous miners consist of a series of large cutting shearers and a self-raising hydraulic system that supports the mineshaft ceiling as sections of coal are removed.

   Wheel tractor scrapers
   

This machine is for transporting earth from one direction to another where it can be seen in the image is not to transport a large amount of land is to carry the specific where it is released by the earth when moving.

8. 
   Bulldozer
   

It is a type of bulldozer that is mainly used for earthmoving, digging and pushing other machines. Although the blade allows a vertical movement of elevation, with this machine it is not possible to load materials on trucks or hoppers, so the movement of the earth is done by dragging.
