高海拔高寒地区露天煤矿工程车辆启动困难问题分析

Analysis on Diffi culties in Starting Construction of Open-pit Coal Mine Engineering Vehicles in High Altitude and Cold Areas

高海拔高寒地区气温较低,平均海拔较高,并且相应的气候干燥,长年降水量少,空气稀薄,风沙大,这对于露天煤矿工程车辆的整体使用性能来说造成较大影响,尤其对于露天煤矿工程车辆发动机的性能来说,低温环境对于发动机的启动性能更造成极大影响。基于此,下述主要就对于高海拔高寒地区露天煤矿工程车辆启动困难的原因进行相应的分析,并针对性的提出提升高海拔高寒地区露天煤矿工程车辆启动困难的解决措施,以期能够更好的提升露天煤矿工程车辆发动机的使用寿命,提升高海拔高寒地区露天煤矿开采发掘效率和露天煤矿工程车辆的使用效率。

In high altitude and cold areas,the temperature is low,the average altitude is high,and the corresponding climate is dry,the annual precipitation is small,the air is thin,and the wind and sand are large,which has a great impact on the overall service performance of engineering vehicles in open-pit coal mine,especially on the engine performance of engineering vehicles in open-pit coal mine,low temperature environment has a great impact on the starting performance of the engine.Based on this,the following mainly analyzes the reasons for the difficulty in starting the vehicles of open-pit coal mine engineering in high-altitude and cold areas,and puts forward the solutions to improve the difficulty in starting the vehicles of open-pit coal mine engineering in high-altitude and cold areas,in order to better improve the service life of the vehicle engine of open-pit coal mine engineering,improve the mining and excavation efficiency of open-pit coal mine in high altitude and cold areas and the use efficiency of engineering vehicles in open-pit coal mine.
