摘要
为了深入研究白垩系地层的冻结规律,现场实测并数值模拟了扎赉诺尔矿区灵东煤矿风井的冻结温度场,分析了其-260 m层位细砂岩的冻结壁温度场发展特性,给出了冻结壁发展速度等关键技术参数,并用数值模拟验证了现场实测规律。对该地区后续矿井的冻结设计、方案优化以及冻结施工具有指导意义。
In order to further study the frozen cretaceous formation, actual measurement and numerical simulation were taken for freezing temperature field of ventilation shaft of Lingdong Coal Mine in Zhalainuoer mining site, analyzed the temperature field development characteristics of frozen tube wall of packsand in - 260m, gave the key technical parameters as the speed of development of freeze walls, and also the numerical simulations verified the site measure rule.The present has instructive significance to subsequent frozen coal mine design, project optimization and freeze construction in the region.
