New construction of rail for underground suspended monorails as an example of typification for deep mining transport in the mines of JSW SA

The article describes the course of design work, leading to the implementation of a new construction of suspended rails rails for the needs of mines belonging to the Jastrzębska Coal Company. The aim of the works, which was one of the stages of the typification of mining excavation equipment within JSW SA, was to improve the material management within the Company, reduce the production costs of rails, improve their anti-corrosion properties and extend the service life of the track. The design of the new construction was also characterized by easy construction, high straightness of the rail and also the possibility of easy adaptation to the increased speed of transport by suspended rail. The overriding objective of all activities is to reduce the cost of extraction. The design work was carried out using a feedback loop, taking into account the necessary corrections in the subsequent stages, resulting from the results of the strength calculations, laboratory tests and comments of the representatives of JSW SA. The final part of the work was the production of a prototype batch of rails, with the load capacity in accordance with the provisions of the applicable regulations, as well as the usable properties corresponding to the needs of mines JSW SA. JSW SA rails, according to the GIG documentation, are available in several variants: straight rails, curved rails, concave or convex rails and transition rails. The JSW rail system is a complement to the JSW rail system, including suspension, pull-outs, turnouts, locks, and track stops from third-party systems that comply with the JSW system's compatibility and compatibility criteria.
