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 A loading mechanism to pick up cut coal and deliver ...

Pillar Extraction using Continuous Miners Introduction ...

Mine lease has areas remaining around longwall blocks too small for longwall extraction but amenable to "remnant mining" with continuous miners. Partial extraction only is permitted because of the potential effect of full extraction on surface features. Small areas of extraction may be required for specific purposes eg stress relief to protect adjacent areas of particular importance. In such ...

Continuous miners - Sandvik Mining and Rock Technology

Sandvik double-pass miners use the most advanced cutting technology for the continuous mining of coal and soft materials. Continuous miners cut and gather the material simultaneously and convey it into shuttle cars, haul trucks or a continuous haulage system. They are typically used for full-scale production in room-and-pillar mining operations. The flameproof design of these machines is certified according

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. When actually cutting, cutting rates are usually more than

Pillar Extraction using Continuous Miners Introduction ...

There are several methods of secondary extraction employing continuous miners, all of which involve splitting the pillars or blocks formed by first workings using minimal (but adequate) short term supports and/or mining a series of short, unsupported "lifts" off long "splits" that are driven with the continuous miner. The length of the lifts are controlled so that the roof remains intact while the continuous miner
