Abstract. Raw material transportation generates a substantial share of costs in the mining industry. Mining companies are therefore determined to improve the effectiveness of their transportation system, focusing on solutions that increase both its energy efficiency and reliability while keeping maintenance costs low. In the underground copper ore operations in Poland's KGHM mines vast and complex belt conveyor systems have been used for horizontal haulage of the run-of-mine ore from mining departments to shafts. Basing upon a long-time experience in the field of analysing, testing, designing and computing of belt conveyor equipment with regard to specific operational conditions, the improvements to the standard design of an underground belt conveyor for ore transportation have been proposed. As the key elements of a belt conveyor, the energy-efficient conveyor belt and optimised carrying idlers have been developed for the new generation of underground conveyors. The proposed solutions were tested individually on the specially constructed test stands in the laboratory and in the experimental belt conveyor that was built up with the use of prototype parts and commissioned for the regular ore haulage in a mining department in the KGHM underground mine "Lubin". Its work was monitored and the recorded operational parameters (loadings, stresses and strains, energy dissipation, belt tracking) were compared with those previously collected on a reference (standard) conveyor. These in-situ measurements have proved that the proposed solutions will return with significant energy savings and lower maintenance costs. Calculations made on the basis of measurement results in the specialized belt conveyor designing software allow to estimate the possible savings if the modernized conveyors supersede the standard ones in a large belt conveying system.

“…Magnetic NTD method can help in the evaluation of steel cord belts condition. The research focused on particular elements of the conveyor: conveyor belts [1][2][3][4], drives [5], idlers [6], gearboxes [7]. One of the NDT-based methods is the DiagBelt system that consists of five modules: a magnetic module, a vision module, a rip detection module, a prediction module, and a safety factor module.…”

The DiagBelt system is the diagnostics device for assessment of a technical condition of conveyor belts. The following paper concerns the magnetic module dedicated for monitoring of belts with steel cords. The system allows scanning of belts with different cord diameters and their density. The speed of the belt also may vary depending on the operating conveyor. Additionally, the system user can change measurement sensitivity and the distance between the measuring probe and the cord. The measurement allowed to determine values of these parameters of which test results are the most reliable. In practice, this enables faster and more accurate assessment of a belt condition, which plays a significant role in the planning maintenance operations. It has a good impact on the continuity of belt operation and belt conveyors reliability. Therefore, it improves the reliability of the whole mining transport system.

“…Reicks 7 in the paper mainly concentrates on the impact of life of bearing and seal design on rotational resistance in detail. Krol et al 8 carried out idler rotational resistance experimental investigation via measurement apparatus; on the contrary, Lu and Lin 9,10 design a test rig that imitates real belt conveyor for measuring idler rotational resistance indirectly. In addition, some researchers concentrate on theoretical approximations in respect of idler diameter and grease viscosity.…”

This paper presents a regression model for prediction of idler rotational resistance on belt conveyor. The advantage of the regression model is that it is created according to the real experimental measurement. Besides, the predicted model corresponds with real operational parameters, such as radial force, rotational speed and measurements, conducted via using a laboratory test facility; several criteria have been used to verify the presented regression model. Finally, by analyzing the regression model combined with influence of radical force and rotational resistance on idler rotational resistance, this paper presents an operable control ideal to achieve energy-saving.
