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 applications.
temperatures from 25 Ctoþ60 C [1]. Conveyor belts are typically used in coalmines, cement and lime industries, paper and sugar mills, in agriculture and in power plants [13]. Because of the widespread use of conveyor belts, there are many standards to be met before they can be put to use in the industry [410].
