Abstract
Description
Technical Field
[0001] The invention relates to the technical field of mine track optimization, in particular to a track laying method for mine development. Background Art
[0002] Mine tracks are mainly used for the transportation of ore, which is transported from the mining face to the ground or other processing sites by mine cars. For example, in some mines in Indonesia, rail transportation systems are used to process broken ore after ring blasting. In addition, tracks are also used to connect tunnels at different levels or areas to form a complex underground transportation network.
[0003] The mining track is an important part of the mine transportation system. Its design and layout directly affect the transportation efficiency and safety of the mine. The mine track consists of two parts: the substructure and the superstructure. The substructure includes the roadbed, drainage ditch and protection and reinforcement facilities; the superstructure includes the ballast, rails, sleepers, connecting parts (such as fish plates, bolts, spring pads, spikes, etc.), safety equipment (such as pull rods, anti-climbers) and turnouts.
[0004] Mine tracks can be divided into main transport lines and general transport lines according to transportation needs. Commonly used rail types include 24kg / m, 18kg / m, 15kg / m, 11kg / m, etc., which are suitable for mines of different sizes and transportation volumes.
[0005] Track line design includes steps such as determining the yard form, drawing a plan layout sketch, calculating line connection points and parameter design, calculating the overall dimensions, and drawing a line layout diagram. When designing, factors such as curve radius, curve angle, and track center distance widening must be considered to ensure the stability and safety of the line.
[0006] The mining track is the core part of the mine transportation system. Its design and maintenance directly affect the production efficiency and safety level of the mine. Through reasonable track design and scientific maintenance management, the transportation capacity and safety of the mine can be effectively improved. Summary of the invention
