摘要
文中研究受采空沉陷区地表移动影响下埋地管道的变形特征,建立煤矿区采动沉陷油气管道的有限元仿真计算模型,对管线方向与工作面推进方向不同夹角开采的影响进行研究,分析了管道的力学行为及变形演化规律,结果表明:夹角为90°工况下管道受地下煤层开采的影响最小,为采空区管道的设计、建设提供参考。
This paper studied the deformation characteristics of buried pipelines under the influence of surface movement in goaf subsidence area. The finite element simulation calculation model of mining subsidence pipelines in coal mine area was established, which studied the influence of different angles between pipeline direction and working face advancing direction, and analyzed the mechanical behavior and deformation evolution law of pipelines. The results show that when the angle is 90°, the pipeline is least affected by underground coal seam mining, which provides a reference basis for the design and construction of goaf pipelines.
