Coal breaker Wikipedia
The coal breaker is a forerunner of the modern coal preparation plant. Generally speaking, a coal tipple was typically used at a bituminous coal mine, where removing impurities was important but sorting by size was only a secondary, minor concern. Coal breakers were always used (with or without a tipple) at anthracite mines.
Underground mining (hard rock) Wikipedia
Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for
List of Mining Equipment Career Trend
Coalminers use electric-powered shuttle cars to transport coal from the coal bed to safer points in the mine. From there, miners can use standard scoops, or haulage vehicles, to drive their loads completely out of the mine. Miners of all types use haulage vehicles for various tasks.

Open-PitSurface MiningUnderground MiningIn-Situ MiningAs the name suggests, open pit mining involves mining minerals or ore that can be found near the surface layer of the site. That being said, some quarries can be over 1000 meters deep. This form of mining doesn’t require tunnelling into the earth and is a simple method of mining that yields high production rates.

What are two types of coal mining Answers
Surface mining is used to produce most of the coal because it is less expensive than underground mining. Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the top soil and layers of rock known as "overburden" to expose the coal seam. Once the mining is finished, the dirt
What Are the Different Types of Mining?
Most surface mines only extend to about 650 feet, after which the underground mining method is used. Room and pillar is a method of underground mining that involves excavating rooms with pillars that hold up the roof and is used for shallow mines. In block caving, miners drill tunnels underneath the ore deposits and then draw the material down.
