抚顺西露天矿入坑主公路设计方案

Comparison of design schemes of the pit entry main highway in Fushun West Open-pit Mine

随着抚顺东露天矿内排土场的发展,电铁排土线需要由西向东发展、由北向南延伸路端。现有的抚顺西露天矿一号、二号主公路系统已经限制了抚顺东露天矿内排土场的发展。为了使抚顺西露天矿坑下主公路彻底避开与抚顺东露天矿电铁线形成交叉,解放西区的排土空间,提出了将抚顺西露天矿主公路挪至南帮的设计方案,对3种建设方案的施工位置选择、施工难度、工程量及投资估算进行综合分析对比。结果表明:大量利用坑下排弃物料进行回填,减少采掘工程量,很大程度上可以节省施工成本。

With the development of internal dump in the east open-pit mine,electric iron row line needs development from west to east and extends from north to south.West Open-pit Mine No.1 and No.2 main road system has restricted the development of internal dump in the east open-pit mine.In order to avoid the main road of west open-pit mine crossing electric wire of the east open-pit mine and release dumping space,the article puts forward the design scheme of moving the mine road to south slope,and analyzes the location choice,construction difficulty,quantity and investment estimation of three construction schemes.The results show that a large number of abandoned materials under the pit are used for backfilling,which can reduce the amount of mining works and save the construction cost to a large extent.
