Examination of hoist drum lining

The safety and reliability of the mine hoisting system are essential for the effective and safe operation of an underground mine, which utilizes a mine shaft for transport and haulage. Thus, high safety and quality standards apply to each element of the hoist, including the winding machine. Therefore, it also concerns the lining of the machine's drum. This element should be characterized by specific parameters, such as hardness and the friction coefficient between the rope and the drum lining. The following article presents a procedure for the examination and results of tests conducted on samples of drum lining provided by two different underground coal mines. The aim of the research was to verify if the lining provided by the mines and previously stored by them for many years complies with the safety requirements and can be installed on the hoist drums. Moreover, the results were verified by EDS tests.
