Belt Tear Detection for Coal Mining Conveyors

Abstract. The belt conveyor is the most commonly used conveying equipment in the coal mining industry. As the core part of the conveyor, the belt is vulnerable to various failures, such as scratches, cracks, wear and tear. Inspection and defect detection is essential for conveyor belts, both in academic research and industrial …

coal preparation plant flow diagram in a coal mine

The scheme used in physical coal cleaning processes varies among coal cleaning plants but can generally be divided into four basic phases: initial preparation, fine coal processing, coarse coal processing, and final preparation. A process flow diagram for a typical coal cleaning plant is presented in Figure 11.10-1.

Coal Processing

Through the flotation process, the mineral matter is separated from the fine coal (which is smaller than 0.5 mm in size). The underflow reports to spiral separators/concentrators, which separate the lighter-density coal from the heavier-density material. The use of dewatering screens is generally the first step in the coal dewatering process.

Coal mining

Highwall mining is an adaptation of auger mining. Instead of an auger hole, an entry into the coal seam is made by a continuous miner, remotely operated from a cabin at the surface. The cut coal is transported by conveyors behind the miner to the outside. Using a television camera, the operator can see and control the miner's progress.
