Electrified Railway from Datong to Qinhuangdao
大同一秦皇岛电气化铁路(Electrified Rail-way from Datong to Qinhuangdao)中国第一条开行重载单元列车、专门运输煤炭的双线电气化铁路。西起山西省大同市,沿途经河北、北京、天津等省市,跨越丰沙、京承、京山等铁路干线,东抵渤海之滨的秦皇岛港,全长653km。年设计运煤能力为1亿t。重载单元运煤列车又称直达运煤专列,是20世纪60年代兴起的一种最先进的运煤列车。整列车由70一200节专用车皮和数个电力机车组成,往返于始终点之间,行进中不解体改编,采用自动化装卸,几台电力机车间采用微机控制,以保持协同牵引,大大提高了运煤效率。 大秦电气化铁路建设分两期完成。第一期工程由大同至河北省三河县大石庄,长4lokm,1985年1月动工,1988年12月建成通车。第二期工程由大石庄至秦皇岛港,长243km,1988年6月动工,1992年12月建成通车。全线所经地区地质复杂,桑干河谷地段河道曲折,山势险峻,桥涵相连,工程艰巨。全路建设实行路 , 、港、矿综合规划,运、装、卸同步配套建设,形成装煤、运煤、卸煤系统一体化的现代运煤大通道。在大同、雁北地区建有18个煤炭集运站,用大型载重卡车把布点分散的煤炭集运到火车站装车。18个集运站设计年发煤能力8000万t,只要装煤敞车供应充分,调度及时,一年可发运煤炭1亿t。18个煤炭集运站全部实现机械化作业,装满万吨列车只需2小时。大秦线煤炭列车由运煤敞车和底开门漏斗车组成,由2一3台电力机车牵引。为配合装运要求,终点秦皇岛港建有中国卸煤效率最高的第三期煤码头,利用翻车机翻卸72节车皮组成的煤炭重载列车只需1.sh,如果各车皮不摘钩卸煤,每小时可翻卸27次。大秦线自1989年开始运煤以来,每年运煤量不断增加。1991年运煤为3 400万t,1993年运煤4 680万t,1994年运煤4 900万t,1995年预计运煤5 500万t。在设备配套齐全、运输组织合理,增开万吨列车等条件下,年运煤能力可达1.5亿t 大秦电气化铁路是中国西煤东运的重要通道,它的建成通车对保证山西煤炭外运,加快神府一东胜煤田、准格尔煤田的开发,缓解华东、华南煤炭供应的紧张状况,发挥了重要作用。(杨洪年)
