虽然蒸汽机车在我国已停止生产,但一些煤炭矿区仍在使用。由于蒸汽机车配件供应困难,检修周期长、费用高,而且蒸汽机车的牵引速度和重量难以提高,对环境污染大,已不适应矿区生产的要求。因此,矿区铁路牵引机车亟须换型更新。通过分析比较内燃机车和电力机车的特点,认为徐州矿务集团铁路机车换型应优先考虑内燃机车。
Although steam locomotives have stopped production in our country, some coal mines are still in use. As the steam locomotive parts supply difficulties, long maintenance cycle, high cost, and the steam locomotive traction speed and weight is difficult to increase, the environmental pollution, has not adapted to the requirements of the mining area. Therefore, the mining area railway locomotives need to change the model. By analyzing and comparing the characteristics of diesel locomotives and electric locomotives, it is considered that the conversion of Xuzhou Mining Group railway locomotive should give priority to diesel locomotives.
