On a Possible Mechanism of Hydrostatic Pressure on Mineshaft Linings in Western China
Geofluids, Volume 2022, Issue 1, 2022., 2022 Reasonable determination of the water pressure on the shaft linings is the key to the optimization design of the vertical shaft of mining. The traditional water pressure calculation model is not suitable for the stratum conditions in western China. A new shaft‐surrounding rock seepage model is proposed based on the coordinated seepage conditions of ...
