“…Conventional measures, such as total working time, are not ideal for assessing the degree of belt wear. In the study [22], new relative measures were introduced, defined as longitudinal (𝐸𝑋 𝑋 ) and transverse (𝐸𝑋 𝑌 ) extent, to enhance the detection of critical threats. The focus was on the transverse extent, as it plays a crucial role in evaluating tensile strength in the area of damage concentration.…”

“…The traditional measure of assessing the technical condition of belts used in the mine, primarily relying on the calendar life of the belt, proved to be significantly less effective compared to the DiagBelt+ system [22]. Relying on visual inspection of belt covers and information about the age of the belt often led to directing belts to refurbishment that were, in reality, in good technical condition and could continue to operate.…”

Faults in steel cords in the core are not visible during routine visual inspections. They can be identified using magnetic diagnostic systems. The article presents an analysis of the impact of the sensitivity threshold of the DiagBelt+ system, the diameter of cords in the core, and the belt speed on the quality of signals representing known damage: cutting of cords, their absence, and a reduction in the cross-section of the cord. The study focused on defects to cords across the belt, as they can weaken the belt's strength and lead to a complete belt failure. The proposed results and analyses contribute to the improvement of the methodology for magnetic examination of the core's condition and the developed diagnostic system DiagBelt+. Consequently, this enhances the reliability and safety of belt conveyors in various industries, including in brown coal mines, where it has been implemented (PGE GiEK SA KWB O/Bełchatów), as well as in coal, limestone, and copper ore mines, where it is used to assess the condition of belts with steel cords.

The proper geometry of belt splices influences their subsequent performance and durability during operation. Despite being such a critical aspect, evaluating the geometry of splices can be challenging, especially after their fabrication and vulcanization. This article presents an approach to diagnosing the geometry of belt splices based on the examination of belts using the DiagBelt+ magnetic system. Through the analysis of practical applications and the benefits derived from monitoring splice geometry, the article emphasizes the importance of diagnosing the geometry of belt splices to improve their quality and performance.
