Feasibility study of speed regulation on motor roads of mining operations

A methodology is proposed for a feasibility study of speed regulation on the motor roads of mining enterprises, which makes it possible to technically and economically assess savings and costs when introducing speed limits for vehicles on the roads of mining operations. A justification is provided by calculating the cost components and saving money, which are subsequently compared with each other. A positive decision on introduction of the speed regulation is made with a positive difference between savings and costs. Application of this methodology allows not only to improve the road safety and reduce the risks of accidents, but also to calculate the financial savings. Application of this methodology allows not only to improve the road safety and reduce the risks of accidents, but also to calculate the financial savings. Studies of speed regulation have been conducted at the Zashulan coal deposit. The length of roads at this operation amounted to 24.3 km. The actual speeds were measured in order to justify the speed norms. The conducted experiment showed that the speed regulation made it possible to increase road safety by almost 15% and allowed to obtain significant absolute normalized savings in the amount of 5.2 million rubles when introducing these measures on the roads of a mining company
