白音华至锦州铁路通道扩能研究

Research on Upgrading of Baiyinhua-Jinzhou Railway Corridor

研究目的:白音华至锦州港铁路通道包括赤大白铁路和锦赤铁路,连接白音华矿区和锦州港煤炭码头,是蒙东地区重要的煤炭下水通道,同时为沿线电厂用煤提供了重要的运输径路。既有白锦铁路通道线路为单线,线路运输能力较小,不能满足通道预测运量的运输需求,需要进行扩能改造。白锦铁路通道为中电投企业投资铁路项目,扩能改造方案需要逐步实施,投资需要逐步完成。研究结论:通过对白锦铁路通道采用不同车型和单双线等不同扩能方案的比较,确定白锦铁路通道采用分期分段逐步的扩能方案。白音华至赤峰段采用逐步复线扩能改造方案,赤峰至锦州港段采用单线扩能方案,同时与白音华至赤峰段复线同期延长车站到发线有效长度至1 050 m。全线的扩能改造采用分段、分期实施,分年度投资呈线型,比较适合企业投资。

Research purposes： The Baiyinhua-Jinzhou Port railway corridor includes the Chifeng-Daban-Baiyinhua Railway and Jinzhou-Chifeng Railway,connecting the Baiyinhua coal mine and the coal dock of the Jinzhou port.This corridor is an important channel for coal transportion between railway and shipping in the east Inner Mongolia Autonomous Region,and it is also the important traffic route for supplying the coal to the power plant along the corridor.The existing Baiyinhua-Jinzhou Railway is single-track railway with small transport capacity,and can not meet the predicted transport demand.So it is necessary to upgrade this railway.The Baiyinhua-Jinzhou Railway is invested by the China Power with implement of the upgrading scheme step by step due to the investment step by step. Research conclusions：Based on the comparison of the different upgrading schemes of adopting the different types of coaches and laying single line or double line for this corridor,it is decided to adopt the scheme of upgrade the section step by step.The scheme of upgrade double line step by step is adopted for the section between Baiyinhua and Chifeng along with expanding the effective length of the arrival and departure lines in station to 1 050 m.The scheme of grading single line step by step is adopted for the section between Chifeng and inzhou.The grading of the whole line is conducted step by step and section by section.In this way,the annual investment is relatively even,and it is suitable for the enterprise＇s investment.
