摘要
为了尽量减少占压煤炭资源,同时降低工程的实施难度,保障铁路的运营安全,论文结合区域工程地质条件、煤矿开采现状以及煤矿开采规划等因素,着重从采深采厚比、最大下沉量和最大水平变形(移动)值、地表最大剩余变形量和采空区影响范围4个方面对铁路经过矿区稳定性进行分析,并经过多方案比选论证后,最终得出线路宜尽量利用煤矿主巷道所在的沿河通道走行这一结论。
In order to minimize the occupation of coal resources, reduce the implementation difficulty of the project and ensure the operation safety of the railway, this paper analyzes the stability of the railway passing through the mining area from four aspects: the ratio of mining depth to mining thickness, the maximum subsidence and the maximum horizontal deformation(movement), the maximum residual deformation of the surface and the influence range of the goaf, After the comparison and demonstration of multiple schemes, it is finally concluded that the line should make full use of the river channel where the main roadway of the coal mine is located.
