In traditional vertical coal bunker systems, a coal-feeder chamber (CFC) must bear the whole weight of the bunker. However, maintenance of CFCs within soft, swelling floor rock is a challenge faced in underground coal mines. Floor-heave control is a complex problem and is still not well-solved. Moreover, there is no report on the construction of bunker without a CFC, especially under such weak ...

Luffing of the boom minimises dust by reducing the distance that material such as coal needs to fall to the top of the stockpile. The boom is luffed upwards as the height of the stockpile increases. Some stackers can rotate the boom. This allows a single stacker to form two stockpiles, one on either side of the conveyor.


Nov 13, 2016· Rotary Cam Limits Switch – It is provided to prevent slewing over yard conveyor conveyor unless boom is sufficiently raised and also prevent excessive lowering of boom over yard conveyor. 7. Long Travel Mechanism. The function of long travel mechanism is to move the stacker from one position to another position in rail track.

This C4 conveyor takes the uncrushed coal back to the impactor thus reducing wastage. The impacted and screened coal is carried on the conveyor 261.12 and passed on to the conveyor 261.13. Here a dust fan 261.44 in placed. The last conveyor in the feeding process is the flight conveyor 261.14, which is also called a plate conveyor.


The scraper conveyor is the key conveying equipment for fully mechanized coal mining. Wear failure of the chute is the main form of failure of the scraper conveyor. In this study, the discrete element method (DEM) was combined with the wear model. The wear mechanism and wear regularity of the chute were explored by tracking the changes in the position of coal particles during the wear process.


Similar to trolley conveyor due to use of discretely spaced carriers transported by an overhead chain; however, the power-and-free conveyor uses two tracks: one powered and the other nonpowered (or free) Carriers can be disengaged from the power chain and accumulated or switched onto spurs


conveyors range from 113 dBA to 119 dBA per 100 m for typical 10,000 TPH 5 m/s coal conveyors. This paper presents results for standard and alternative idler roll designs, referred to as "low noise" and "super low noise" conveyors. Such conveyors produce sound power levels of 107 dBA and 101 dBA per 100 m respectively, while
