In the coal mining production system, rails play an irreplaceable and important role and are key facilities to ensure efficient and safe transportation of coal mines.
The underground transportation routes of coal mines are complex, and rails play a core "role". It provides a solid running track for mine cars. Whether it is the transportation of coal and gangue, or the transfer of equipment and materials, it is inseparable from the support of rails. Through rails, mine cars can travel smoothly along the established route, transport the mined coal to the ground continuously, and accurately deliver the required materials to the operation area, greatly improving transportation efficiency. Taking the common narrow-gauge railway system as an example, rails with a gauge of 600 mm or 900 mm, with suitable mine cars, can flexibly shuttle in the narrow space underground to meet various transportation needs.
The selection of rail models is crucial in the coal mining field. Transportation volume, vehicle axle weight, driving speed, etc. are all key factors in determining the selection of rails. In the main transportation lanes with frequent transportation and heavy vehicle loads, heavy rails of 24kg/m and above are generally selected, such as 30kg/m and 38kg/m rails. These rails have high strength and strong bearing capacity, can withstand frequent heavy load impacts, and ensure safe and stable transportation. In lanes such as uphill and downhill lanes with small transportation volume and slow driving speed, 15-18kg/m light rails are sufficient to meet transportation needs and reasonably control costs.
The coal mining environment is harsh, and rails face many challenges such as corrosion and wear. To deal with these problems, coal mines usually use rails with anti-corrosion properties and regularly carry out anti-rust treatment, such as applying anti-corrosion paint. For severely worn parts, wear-resistant rails are used or the surface of the rails is hardened to extend the service life of the rails. At the same time, in order to reduce the impact and wear at the joints, some coal mines also use long rail welding technology to weld ordinary rails into long rails, reduce the number of joints, and improve the smoothness of the rails, which not only reduces the maintenance workload, but also improves the stability and safety of transportation. With its reliable performance, rails have built an efficient transportation network in the coal mining field, which has effectively promoted the sustainable development of coal mining production.
