Conventional coal mining. Conventional underground coal mining relies upon the use of continuous miners in order to extract coal reserves from underground coal seams. In combination with the continuous miners, shuttle cars are used to transport the extracted coal from the face to a transfer point (feeder breaker).
Continuous mining machines are large, high-powered scrapers that extract coal from mines' seams. The new rule will require mine operators to equip these machines with proximity detection systems, which use electronic sensors on both mining machines and miners to detect motion or the location of one object relative to another.
Tuesday, May 20, 2014. On May 12, 2014, two mine workers—a continuous mining machine operator and a roof bolting machine operator—tragically lost their lives while working at the Brody Mine No. 1 in Boone County, West ia.

List of Mining Equipment Career Trend. Subterranean coal miners use the machines to scrape coal from coal beds. In particularly dangerous situations, workers control robotic continuous miners remotely.
COAL MINE FATALITY - On Tuesday, June 13, 2017, a 32-year-old continuous mining machine operator was fatally injured when he was pinned between the cutter head of a remote controlled continuous mining machine and the coal rib. The victim was backing the continuous mining machine from the working face when the accident occurred.
Occupational Employment and Wages, May 2019 47-5041 Continuous Mining Machine Operators. Operate self-propelled mining machines that rip coal, metal and nonmetal ores, rock, stone, or sand from the mine face and load it onto conveyors or into shuttle cars in a continuous operation.
A majority of continuous mining machines employ a water spray system and a machine mounted flooded-bed scrubber to suppress and capture dust during coal mining. These machine mounted dust control systems must be designed to function within the localized face ventilation system at the mining section to control both dust and methane.
Coal mining - Wikipedia. This type of mining accounts for less than 5 percent of total underground production in the US today. [citation needed] Shortwall mining, a method currently accounting for less than 1 percent of deep coal production, involves the use of a continuous mining machine with movable roof supports, similar to longwall.
(5) June 13, 2017 Rockwell Mining, LLC, Gateway Eagle Mine (D00008482C) Boone County, WV The victim was operating a continuous mining machine and was pinned by the machine cutter head against the coal mine rib resulting in fatal injuries. Investigative Report
FIGURE F-1 Schematic of a room-and-pillar coal mine section. SOURCE: Arch Coal, Inc., 2012. FIGURE F-2 Details of the longwall face. SOURCE: EIA, 1995. There are several variations of each method. However, ever since the introduction of continuous miners in the late 1940s, room-and-pillar continuous mining has been gaining ground over conventional room-and-pillar mining.

Navigation and control of continuous mining systems for coal mining ... that will allow remote-controlled operation of mechanized equipment normally used in underground room-and-pillar coal mining, thereby permitting workers to be located away from the hazardous coal extraction area (the face). As part of this program, advanced machine ...
Laboratory and in-mine tests have indicated that, with modification, this sensor can meet the humidity and vibration requirements for underground coal mine use. NIOSH is continuing that effort by developing prototypes of a continuous dust monitor based on this technology.
Nov 28, 2018· The continuous miner deliberately leaves undisturbed pillars of rock and coal in the mining area to create natural supports for the ceiling. This is known as "room and pillar" mining. When most of the coal seam has been extracted, the pillars then are mined one by one, allowing the roof to naturally cave in.
This is one of the key roles for the IoT (Internet of Things) in mining. Continuous miners used in underground coal mining gather data from over 300 sensors on each machine, with each sensor capturing and transmitting data every second. that's a lot of data!
