长三角高速铁路网建设对江苏省煤炭铁路运输能力的影响

铁路运输是我国煤炭运输的重要方式。我国高速铁路的建设不仅对经济社会发展产生重大影响，也释放出一定的运能，促进铁路煤炭运输能力的提升。文章以江苏省为实证区域，针对江苏省铁路运煤特点，构建计算方法，估算了长三角高速铁路建设之前，京沪、沪宁等高速铁路通车后，以及长三角高速铁路网初步形成后江苏省主要铁路运煤线路的运输能力。结果表明：在长三角高速铁路建设之前，江苏铁路运煤线路受制于大量开行高等级旅客列车、线路技术等级低、施工维护等因素，煤炭运输压力巨大；随着长三角高铁建设的不断推进，一些铁路运煤线路运能得到释放；今后随着高速铁路网络的形成，“客货分线”得以实现，加上规划新建的铁路，铁路运煤能力将有较大提升。

Impact of Construction of High-Speed Railway Network in Yangtze River Delta on Coal Railway Transport in Jiangsu

Railway transport is an important way of coal transport in China. Construction of high-speed railway in China not only has a significant impact on economic and social development but also releases certain transport capacity. This paper concerns about the features of coal railway transport in Jiangsu Province,then estimates the capacities of main coal railway transport lines in Jiangsu at three periods: before the construction of high-speed railway in Yangtze River Delta, after the opening of the several high-speed railway lines such as Beijing-Shanghai High Speed Railway and Nanjing-Shanghai High Speed Railway and after the formation of the high speed railway network in Yangtze River Delta. The result indicates that before the construction of high speed railway network in Yangtze River Delta, coal railway transport lines were limited by a number of factors such as running many high-level passenger trains, having low technical levels, keeping regular railway maintenance etc. Accordingly the pressure of coal transport in Jiangsu is extremely high. However, with the continuous construction of high speed railway network in Yangtze River Delta, the transport capacities of some coal transport railways are released. In the future, with the formation of high speed railway network in Yangtze River Delta, the coal transport capacities of railway will be improved by separating the passenger rails from freight rails as well as planning and building new coal transport rails.
