二十年来,鲁尔矿区平均采深增加了200多米。随着采深加大,岩层温度和井下风流中的热量也增大,必须采取降温措施。而柴油机所释放的热量又非常可观,它比电力驱动装置释放的热量要增加许多倍。到目前为止,对井下柴油机车运输的研究,均以机车特性曲线为出发点。此特性曲线由柴油机和减速器特性曲线中导出。借助 For two decades, the average mining depth in the Ruhr mining area has increased by more than 200 meters. With the deepening of mining depth, the temperature in the formation and the heat in the underground wind flow also increase, and cooling measures must be taken. Diesel engines, on the other hand, generate significant heat, which is many times greater than the heat released by electric drives. So far, the research on the underground diesel locomotive transportation has taken the locomotive characteristic curve as the starting point. This characteristic is derived from the diesel and gear unit characteristics. With
