Abstract:At present, compared to the advanced foreign coal mining countries, there is a great gap in China"s coal mine auxiliary transportation condition, it’s inharmonious between the backward of auxiliary transportation and the high speed developing of mining technology and the significantly improving of the coal mining mechanization level. Therefore, it’s extremely urgent to improve the way of auxiliary transportation. An integration of mine is still using the traditional auxiliary transportation system in Shanxi LinFen, which exists the operational links, slow speed, low efficiency, occupation of personnel and equipment and safety, adaptability, mobility is poor and so on, that has become the weak link of restricting the development of production. In view of the above understanding, the purpose of the optimized design scheme is to transform the existing way of underground rail auxiliary transportation into Trackless Rubber-Tyred Vehicle transportation, through the optimized of transformation, we achieved good results in the production, transportation and safety aspects.
