Abstract

Changes of damage to the belt core that are not controlled during the exploitation can lead to dangerous accumulation of the defects (strains) in the cross cross-section. It can lead to serious weakness and even rupture of the belt. Early detection of the mic rodamage of the covers and evaluation of the increase speed of the damage allows the user to plan maintenance more precisely. Furthermore, it allows more effective cost management when conveyor belt maintenance is scheduled. In this paper, geometric data o f the belt core damage working in the underground mine have been analyzed. It was proven that change of the damage increase is significantly higher in the direction perpendicular to the axis of the movement. Damage locations are random on the whole belt. H owever, they can be analyzed using statistical methods. Data analysis in the Statgraphics program proved that the distribution of the damage values in the axis of the belt movement has loglogistic distribution. Non -destructive testing of the belt showed n ew damage formation and changes in the size of already existing damage. Amount of the damage per meter and for the whole loop of the belt has been proven insufficient for the evaluation of the belt condition. Quantitative information should be extended wit h the area of the damage. Data analysis proved that increase of the amount of the damage is usually not correlated with the change of the overall area of the damage. In some cases, the amount of damage decreases in contradiction to the overall area. Detail ed analysis has shown that it is a result of multiple defects being close to each other.
