虎豹湾矿井冻结温度场数值模拟与实测对比

The Comparative Analysis of the Numerical Simulation and Actual Measurement of the Freezing Temperature Field in HuBaowan Mine

内蒙古鄂尔多斯盆地已探明优质煤炭储量巨大,其表面覆盖地层主要包括侏罗系中统和白垩系。为深入研究侏罗系地层冻结规律,现场实测了内蒙古纳林河矿区虎豹湾煤矿主井冻结温度场。结合-330m层位粉砂岩热物理参数,通过ANSYS数值模拟的方法分析冻结壁温度场的发展规律,并得到了冻结壁发展速率等关键技术参数,数值模拟验证了实测的冻结壁发展规律,同时数值模拟应用在侏罗系冻结施工中冻结壁的发展规律的研究的可行性也得到了验证。此次研究对该地区的矿井冻结设计、优化及施工具有指导意义。

It has ascertained huge reserves of coal in ordos basin Inner Mongolia.the surface coverage formation mainly includes the Jurassic and cretaceous ZhongTong.For further study on the Jurassic formation freezing rule,actual measurement were taken for the freezing temperature field of main shaft of HuBaowan mine coal in NaLinhe mining.Combining thermal physical parameters of aleuvite in-330m,with the way of ANSYS numerical simulation analysis the developmentol law of the temperature field of the frozen wall,and some key technology parameters such as the development rate of frozen wall are gotten.Numerical simulation verified the measured frozen al wall development law,and the feasibility of the numerical simulation application in the study of the development law of frozen wall is verified.The researcn has instructive significance to the frozen coal mine design,project optimization and construction for the subsequent.
