摘要
以通过煤矿塌陷区的架空敷设供热管道为研究对象,对通过塌陷区边界采用常规非预应力安装的管道进行了危险性分析,采取了适当缩短支架间距及预应力安装的解决方法。
Taking the overhead,heating pipeline passing across the coal mine subsidence area as research object, the risk of conventionally installed （without prestress ） pipeline passing across the boundary of subsidence area is analyzed..The solving methods include appropriately shortening the space between the supports and using prestress installation.
