| Abstract: | Seen as a stability problem of a long column under the action of dead we-ight,the stability of coal mine veritcal shaft during its construction is discu-ssed.By taking into account the effect of drilling mud around the shaft,anon-conservative physical model is established.Numerical analysis is made toshow the influence that the drilling mud may have on the shaft stability.Someunusual features of the problem are explored. |
