Analysis of Frozen Drilling Surrounding Rock Temperature Field about Weakly Cemented Soft Rock

Abstract:

Article Preview

This paper mainly introduced the monitoring scheme of one mine’s wind well in Inner Mongolia. By analyzing the monitoring data at different depth, rules of the freezing temperature field were drawn. Fitting the monitoring data linearly at freezing and thawing phrase respectively, the experience formula of time prediction at the two phases were obtained. Meanwhile the temperature diffusion coefficient of sandstone and mudstone layers were revised, which can provide scientific basis for some similiar shaft construction.
