摘要:
針對淺埋輸氣管道建設與煤炭資源壓覆的矛盾將愈來愈突出,開展了采動條件下淺埋輸氣管線變形影響問題研究,以新開采的某煤礦為例,采用概率積分法模型分析預測地下采煤引起的輸氣管線變形情況,并采用有限元計算的方法對管線的變形進行安全評估。結果表明工作面開采后,預測受采動影響的管線長度約為2 250 m,管線沿線最大下沉為924 mm,管線所承載的最大應力為55.962 MPa,遠低于管線的屈服強度,管線運行安全。
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.
