10 Different Types of Mining Operations and Mines

Longwall mining involves underground coal mining, whereby a long wall of coal is mined via a single slice, and the slice is usually from two feet to a little over three feet thick The block of coal being mined, which is called the longwall panel, is normally approximately 270 to 430 yards in Coal mining Coal mining Underground mining: In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities Coal mining Underground mining BritannicaThis bibliography lists materials on coal mining and related resources contained in the library of Southeast Community College (Kentucky) The guide is organized in six sections Hustrulid, W A, ed Underground Mining Methods Handbook New York: Society of Mining Engineers of the American Institute of MiningDOCUMENT RESUME ED 314 600 CE 053 933 AUTHOR Zhang, Underground Coal Mining Methods and Engineering Dust Controls An underground mine consists of the portals (entrance and exits to the mines), mains, submains, panels, and working faces The panels are the working sections of the production operation Depending on the mining methodAppendix F: Underground Coal Mining Methods and Underground Coal Mining Methods to Abate Water Pollution: A State of the Art Literature Review Coal Research Bureau West Virginia University Morgantown, West Virginia 26506 for the Underground Coal Mining Methods to Abate Water Pollution

The Actual Difference Between Surface and Underground Mining

Underground mining is used for gold, platinum, zinc, lead, and increasingly, coal As can be seen, surface mining is much more advantageous than its counterpart However, when an outcropping ore body stretches deep inside the Earth, surface methods can be used to begin the mining operation, which then need to be continued further by underground May 11, 2016 Here is the real miners working without technologyReal Miners, Old Method Underground Coal Mining from Turkey This video is taken in Real Miners, Old Method Underground Coal Mining YouTubeAug 30, 2012 Underground mining coal extraction methods can generally be divided into two categories: room and pillar mines and longwall mines The type of extraction practiced is dictated by the characteristics of the coal seam and its related geology Generally, longwall mining is restricted to seams with uniform geology and coal Mining 101 West Virginia Coal AssociationShortwall Mining This method of mining was developed in the late 1960's to take advantage of the then recent development of suitable hydraulic longwall supports, coupled with the productivity and low Shortwall Mining Introduction underground COALThe Bureau of Mines embarked on a long term, highrisk research and development program in the mid1970's to introduce new technology into the mining industry to improve productivity and reduce the cost of coal Innovation in underground coal mining equipment and techniques Full text of "Coal extraction, transport, and logistics
