| Abstract |
The local buckling of a drift with a composite lining
is investigated in the case of the elastoplastic behavior
of the rock and the lining materials. The investigation
is based on 3D buckling equations. The influence of the rock
and lining parameters on the
critical contact pressure is assessed.
Rock mechanics problems related to mine working involve the analysis
of local buckling of the rock near drifts in the case of elastoplastic
deformation of the materials [1-4]. This analysis involves the determination
of the optimal contact pressure on the lining and the cross-sectional
dimensions of the drift. Unlike [2], the present paper deals with
the investigation of the local buckling of the rock in the drift near-shaft
zone, with the composite structure of the lining being taken into account.
This investigation is based on the exact 3D equations [5].
The idea of the determination of the rock pressure by solving
the buckling problem is due to L. V. Ershov. |
