24-04-1984· The present invention is a continuous miner which is able to operate both in surface mines to excavate horizontal layers of earth and ore for processing, as well as in underground mines to unearth arcuate layers in front of the miner. The continuous miner includes a cutting blade which is mounted at the lower end of a resonant beam.
moving continuous miner or beyond the supported roof for a better view while coal cutting or tram ming. Adding to this hazard is restricted work space with reduced visibility. The work environment in found in low coal seams of 15.7 cm puts continuous miner operators and helpers in awkward work pos

Ein Continuous Miner ist eine Gewinnungsmaschine, die im Bergbau Untertage zur Gewinnung von Steinsalz, Gips und Steinkohle eingesetzt wird. Der Continuous Miner gehört aufgrund seiner Bauform zu den Umfangfräsen. Es gibt Continuous Miner in unterschiedlichen Größen. Continuous Miner sind geeignet für eine Ortsbrust mit kleinem Querschnitt.
Continuous Miners Home – Underground Mining – Room Pillar – Continuous Miners The Caterpillar line of Continuous Miners includes products for both soft and hard cutting applications, in any seam thickness — for seams as low as 810 mm (32 in) up to 4.7 m (15.4 ft).
The continuous miner shears coal panels 150 to 200 feet (45 to 60 metres) wide and more than a half-mile (1 km) long, having regard to factors such as geological strata. [ citation needed ] Retreat mining is a method in which the pillars or coal ribs used to hold up the mine roof are extracted; allowing the mine roof to collapse as the mining works back towards the entrance.
The 12CM12 continuous miner, with a solid-head cutting head system, features a 965 mm (38 in.) conveyor width for standard width entry applications. The 12CM12, as well as all 12CM series continuous miners, are designed specifically to make efficient use of the additional space available in higher seam heights by offering improved outboard access to all major components.

Continuous Miners. A machine with a large rotating steel drum equipped with tungsten carbide teeth that scrape coal from the seam. Operating in a “room and pillar” system – where the mine is divided into a series of 20-to-30 foot “rooms” or work areas cut into the coalbed – it can mine as much as five tons of coal a minute – more than a miner of the 1920s would produce in an ...
