Remote-controlled continuous miners are used to work in a variety of difficult seams and conditions, and robotic versions controlled by computers are becoming increasingly common. Continuous mining is a misnomer, as room and pillar coal mining is very cyclical. In the US, one can generally cut up to around 20 feet (6 meters).

Note the 40-ton CAT wheeled dozer at lower left for size comparison A bucket-wheel excavator (BWE) is a large heavy equipment machine used in surface mining . Their primary function is that of a continuous digging machine in large-scale open-pit mining operations, removing thousands of tons of overburden a day.
Mining engineers use the principles of math and science to develop philosophical solutions to technical problems for miners. In most cases, a bachelor's degree in engineering, mining engineering or geological engineering is required. Because technology is constantly changing, miners and mining engineers need to continue their education. [4]
The miners, who were all volunteering their time, were too sheepish about building a highway without legal permission to speak on the record. Logan Campbell, 37, speaks about the work that has ...
The coal industry asserts that surface mining techniques, such as mountaintop removal, are safer for miners than sending miners underground. [28] Proponents argue that in certain geologic areas, MTR and similar forms of surface mining allow the only access to thin seams of coal that traditional underground mining would not be able to mine.
Cart from 16th century, found in Transylvania A dumper minecart used in the Basque Country, currently at the Minery Museum.. A minecart, mine cart, or mine car (or more rarely mine trolley or mine hutch) is a type of rolling stock found on a mine railway, used for transporting ore and materials procured in the process of traditional mining.
During 2006, 72 miners lost their lives at work, 47 by coal mining. The majority of these fatalities occurred in Kentucky and West Virginia, including the Sago Mine Disaster. [29] [30] On April 5, 2010, in the Upper Big Branch Mine disaster an underground explosion caused the deaths of 29 miners.
