【 摘 要 】

In the production practice, the key parts of scraper conveyor have a short life span and a high failure rate, which seriously restricts the production efficiency of coal mines in China. In order to ensure the high efficient and safe mining of coal resources, it is urgent to study the reliability of heavy scraper conveyor. With the development of deep and large coal mine in our country, the reliability of scraper conveyor is more and more high. In this paper, the structure of scraper chain transmission system is analyzed firstly, and then simulates the service age and reliability of the scraper chain system. Finally, it is concluded that when the scraper chain system transports different materials, the order of oscillation of the system reliability from long to short is lignite, coking coal, anthracite and gangue, and when entering the final plateau stage, the order of reliability from high to low is also lignite, coking coal, anthracite and gangue.
