山西中南部铁路莱芜绕避采空区改线方案研究

             

摘要

South central railway of Shanxi passes through Laiwu mining area. Due to illegal exploitation of Chuiyang iron mine towards railway, the railway has to pass through affected area of mined out area, thus suffering significant security risks. Based on extensive collection and absorption of data pertinent to Laiwu mining area and regional surface movement tendency, engineering geological analogy and ground collapse movement angle method are adopted to find a safe and sound railway corridor through mining area with reference to such factors as deposits hosting condition, geological structure of the region and mining methods. Through scheme comparison, the scheme to go along Huihe Avenue is recommended, which satisfies safe railway operation, confirms with city layout, and bypasses Gangli Village and other major resettlement projects. Ground collapse movement angle method is acceptable for railway route selection through mining area to shorten the distance of the railway corridor and reduce significantly occupied mineral resources, which provides certain guidance to railway route selection in mining area.%山西中南部铁路线路穿越莱芜矿区,由于垂杨铁矿非法向铁路方向开采,导致铁路线路走行在采空区影响区内,存在重大安全隐患。在广泛收集并消化吸收莱芜矿区及区域地表移动规律资料的基础上,结合本地区矿床赋存条件、地质构造和开采方式等因素,按工程地质类比法,采用地面塌陷移动角的方法,找出安全可靠的铁路廊道通过矿区。通过方案比选,推荐满足铁路运营安全,符合城市规划布局,绕避了港里村等重大拆迁工程,工程可实施性较强的沿汇合大道方案。矿区铁路可采用地面塌陷移动角的方法进行铁路选线,可有效缩短铁路安全廊道的距离,大大减少压覆矿藏的数量,对矿区铁路选线有一定指导价值。
