某地下矿山开采对拟建天然气管道工程影响分析

Analysis on the Influence of an Underground Mining on the Proposed Natural Gas Pipeline Project

拟建天然气管道工程设计在某地下矿山沿矿界北侧外围敷设,管道线路与矿权界限的最近水平距离约63 m,距矿体开采边界最近水平距离约124 m。为了分析某地下矿山采空区对拟建天然气管道施工的影响,采用基于DIMINE与MIDAS/GTS NX有限元软件进行三维有限元数值模拟计算,揭示某地下矿山采空区对拟建天然气管道建设的主要影响因素。

The proposed natural gas pipeline engineering design is laid in a underground mine along the northern side of the ore boundary.The nearest horizontal distance between the pipeline line and the mining right boundary is about 63 m and the nearest horizontal distance from the mining boundary of the orebody is about 124 m.In order to analyze the influence of the goaf of an underground mine on the construction of the proposed natural gas pipeline,the three-dimensional finite element numerical simulation was carried out based on DIMINE and MIDAS/GTS NX finite element software,which revealed the main influence factors of goaf in a underground mine on the construction of the proposed natural gas pipeline.
