许多矿山在以尽可能高的效率从工作面运输产品的同时,遇到了不能适时运送人员和物料的问题。在英国的煤矿,竖井与工作面间运距不断加大的趋势要求人车列车以很高的速度运行。某矿的开拓工程,工人从竖井至工作面的行程达8公里,为此,制造了新型机车列车,用5节车箱可运送150人。该机车以30公里/小时的速度运行,最高速度达50公里/小时。提高行车速度,使工人能有更多时间在工作面工作。皮克罗斯
While many mines transport products from the work surface with the highest possible efficiency, they have encountered the problem of not being able to deliver personnel and materials in due course. In the UK coal mines, the trend of increasing distance between the shaft and the work surface requires that people and vehicles run at high speed. A mine pioneering project, the workers from the shaft to the face of the journey of up to 8 km, to create a new locomotive train, with 5 car can transport 150 people. The locomotive runs at a speed of 30 km / h with a top speed of 50 km / h. Increase driving speed and allow workers more time to work on the work surface. Piccross
