摘要
以袁大滩煤矿主斜井治理工程为背景,研究了渗流地层斜井帷幕冻结的温度场发展规律。通过现场实测和数值模拟主斜井治理工程第1段-70 m细砂层在地下水渗流作用下的冻结壁温度场发展特性,为类似工程的设计与施工提供了借鉴。
The development of the temperature field of the inclined shaft in the seepage stratum is studied with the background of the main inclined shaft control project in Yuandatan coal mine. The development characteristics of freezing temperature field in -70 m fine sand layer of the first section of main inclined shaft control project under the action of groundwater seepage are studied by field measurement and numerical simulation, which provides reference for the design and construction of similar projects.
