·In the United States approximately 1/3 of annual coal production comes from underground mines Almost all underground coal production is produced by continuous miners and longwall shearers As mechanical mining technologies advance more underground non coal mining operations utilize mechanical methods for mining and development The majority of
Vibrational energy transmission in underground continuous mining
·Since 1945 the continuous miner has been one of the most widely utilized cutting machines in underground mines [1] It has a cylinder shaped cutter drum with conical bits lacing for cutting coal/rock Fig 1 Continuous miners have become increasingly powerful and heavy in recent decades with machines such as the 12HM series weighing approximately 170
Continuous miners Introduction underground COAL
The term "continuous" as applied to development machines has been one of the biggest misnomers used for mining equipment because on development they are usually anything but continuously cutting The main delays mostly occur while roof support is installed and often waiting for shuttle cars to return from their discharge point for reloading
