Aug 26, 2020· Longwall mining machines are about 800 feet (240 meters) in width and 5 to 10 feet (1.5 to 3 meters) tall. The miners extract "panels" -- rectangular blocks of coal as wide as the mining machinery and as long as 12,000 feet (3,650 meters). Massive shearers cut coal from a wall face, which falls onto a conveyor belt for removal. As the miner
Apr 29, 2016· Highwall mining systems can sometimes be the final mining method used in open cut mines, or it can serve as a means of transition, with low capital cost, from surface mining to underground mining. From the results of a series of laboratory tests and numerical analyses, stability of openings/pillars in the auger mining system is higher than that

Shortwall 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 capital cost of continuous miners and shuttle cars.
longwall mining Mining. a mining method in which very long rectangular blocks of coal are defined during the development stage of the mine and then extracted in a single continuous operation by an automated cutting head moving parallel to the coal face.When the coal is cut, the working area is protected by a movable, powered roof support system. As the face progresses, the immediate roof
Longwall mining systems are capable of producing significant outputs from a single longwall face 8 million tones per annum or more. When operating correctly the coal is mined in a systematic, relatively continuous and repetitive process which is ideal for strata control and for associated mining operations
American Highwall Systems, Inc. (AHS) provides a radical alternative to current highwall mining equipment. With AHS highwall mining systems, mine operators can mine previously unrecoverable coal seams of various heights and slopes and unmatched seam penetrations.
mines. Currently, there may be up to 60 highwall mining systems and as many as 150 auger mining systems operating in the nation’s surface coal mines. Recent estimates suggest that upwards of 45 million clean tons representing about 4% of total U.S. coal production comes from these methods (1). Volkwein, et al., (2) review the evolution of auger
Longwall automation benefits in underground mining go beyond increased production. Longwall system automation is moving toward full gate end automation, teleremote operation and, ultimately, fully autonomous operation. That means increased safety and efficiency as well.
Other articles where Shortwall method is discussed: coal mining: Shortwall mining: In the shortwall mining method, the layout is similar to the longwall method except that the block of coal is not more than 100 metres wide. Furthermore, the slices are as much as three metres thick and are taken by a continuous miner.
Plow systems from Caterpillar make the plow the mining system of choice for low and medium seams under 1.8 m (5.9 ft). With features offered only by Caterpillar, our plow systems exceed the production performance of shearers and offer future-oriented solutions for hard-coal mining.
