摘要
以陕北某煤矿既有运煤专用线为背景,为缓解其运输压力,在研究分析该线既有运输能力的现状和特征的基础上,根据历史运量统计数据,利用时间序列模型对其远期运量进行了预测。同时,考虑到煤矿正在进行产业转换,业已开工建设的焦化甲醇工程将对专用线的运量及运输结构产生不可忽视的影响。基于上述考虑,对该既有线提出相应的改扩建措施:增设小型会让站和下行方向采用双机牵引。研究结果表明,改建措施能显著提高线路限制区间的运输能力,从而提高整条线路的运输能力,满足煤炭以及相关副产品的运输需要。
This paper takes an existing special railway line of a coal mine in northern Shanxi as the research object. In order to release the transportation pressure, based on analyzing current transport capacity and its characteristics, the long-term freight capacity was forecasted using time series model according to the historical transportation statistics. Meanwhile, considering the coal mine is in the process of industrial transformation, and the coking methanol project under construction will greatly influence the transport capacity and structure of the special railway, some corresponding reconstruction measures were proposed due to the above concerns, namely, building more small crossing stations and using dual- locomotive traction in down direction. The research results showed that the measures can improve the transport capacity of restricted sections obviously, and thereby the transport capacity of the whole line will be increased to meet the transportation needs of coal and related products.
