摘要:
针对浅埋输气管道建设与煤炭资源压覆的矛盾将愈来愈突出,开展了采动条件下浅埋输气管线变形影响问题研究,以新开采的某煤矿为例,采用概率积分法模型分析预测地下采煤引起的输气管线变形情况,并采用有限元计算的方法对管线的变形进行安全评估。结果表明工作面开采后,预测受采动影响的管线长度约为2 250 m,管线沿线最大下沉为924 mm,管线所承载的最大应力为55.962 MPa,远低于管线的屈服强度,管线运行安全。
Abstract:
The contradiction between the construction of gas pipeline and the coal resources becomes more and more prominent. It is necessary and urgent to carry out the study on the deformation of the gas pipeline under the mining conditions. In this paper, taking the new mine as an example, the probability integral method model is used to predict the deformation of gas pipeline and the safety assessment of pipeline deformation is carried out by finite element method. The results show that the length of the pipeline affected by the mining is about 2 250 m. The predicted maximum subsidence along the pipeline is 924 mm and the maximum stress of the pipeline is 55.962 MPa, which is much lower than the yield strength of the pipeline. So the pipeline can operate safely.
