Continuous miners Introduction underground COAL

Continuous miners. Though there are many variations in design, continuous miners mostly consist of five main elements: A central body to carry all other components mounted on some type of drive mechanism to provide mobility (most commonly caterpillar tracks). A "cutting head" usually rotating drum(s) and/or chains with cutting picks attached

Mechatronic model of continuous miner cutting drum

2016-8-1  A typical continuous miner consists of a drive and a cutting system. The boom with the cutting drum is connected to the body by a rotational joint. The hydraulic actuator lifts up the boom while electric motor, usually installed on the boom, drives the cutting drum. These kinematic processes cause the interaction of the cutting tools with the rock.

Tests on the cutting performance of a continuous miner

Experience with the 34 continuous miners operating in South Africa in December 1978 showed that, on average, 40 per cent of the total downtime for these machines was due to mechanical failures associated with cuttingll. This is double the figure for continuous miners in the D.S.A.12. In addition, the instantaneous cutting rate

Continuous Miners Coal Education

2018-1-5  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

Mechatronic model of continuous miner cutting drum

2016-8-1  The continuous miner's boom with cutting drum is a mechatronic system involving electromechanical driveline which interacts with rocks. The forces needed for the rock-cutting process are dependent on many factors. However, in each case the value of these loads has a significant influence on the mechanical structure and electrical system.

Introduction to Shortwall Mining OneMine

Shortwall mining is a method of mining in which a continuous miner cuts and loads from the short end of a rectangular pillar of coal while hydraulically powered self-advancing roof supports provide protective cover. Characteristics of a shortwall system include panel di¬mensions (Fig. 1) of 610 to 1219 m (2000 to 4000 ft) in length, face

How Underground Mining Works HowStuffWorks

The continuous miner drills into the rock until it forms an excavated room, perhaps 20 to 30 feet (6 to 9 meters), leaving in place a rock pillar to support the "roof" [source: United Mine Workers of America]. The machine moves through the ore, creating rooms and pillars, until the full deposit is covered.
