摘要
矿下埋地天然气管道对井下移动变形值的响应与敏感性具有显著的特殊性.通过研究矿下施工事件对埋地天然气管道变形的影响设计了一套微震监测系统,采取实时智能在线观察井下活动对埋地管道的影响,如地表下沉、水平移动、水平变形等事件;基于埋地管道采动变形特征,建立了半定量风险评估指标体系,以此来对事件的发生进行预警和防护.系统测试结果表明,微震监测系统可以很好地适应矿下活动对埋地天然气管道的影响监测需求.
Abstract
The response and sensitivity of underground natural gas pipelines to underground movement deformation values have significant specificity.This article designs a microseismic monitoring system by studying the impact of underground construction events on the deformation of buried natural gas pipelines.It adopts real-time intelligent online observation of the impact of underground activities on buried pipelines,such as surface subsidence,horizontal movement,and horizontal deformation events;Based on the deformation characteristics of buried pipelines during mining,a semi quantitative risk assessment index system was established to provide early warning and protection for the occurrence of events.The system test results show that the microseismic monitoring system can well adapt to the monitoring needs of underground activities on buried natural gas pipelines.
