Keywords: special strata; double layer shaft; elastic analysis
Abstract:A stress calculation method has been established for the double layer shaft in special strata.
From the engineering perspective, although the outer layer of the double layer shaft is in a bad safety state, the plastic interlayer can still proof the water when the outer layer ruptured, and the inner layer of the double layer shaft is in a good safety state, it can still bear the external loads at this time, therefore the application of this double layer shaft is advantageous for the safety production of the mine, and the outer layer of the shaft is the fragile part that needs to be repaired primarily, which is different from the single layer shaft.
