The paper deals with the subject of rehabilitation and mechanical modernization extraction plant within mining operation salt mine from Slanic Prahova region. serves 23 August shaft Unirea mine, also this has been converted into a tourist mine. installation consists in change cutting wheels tower due to excessive degradation, requiring redesign under strict conditions, extension saline water sy...

The main intake shaft in the mine serves as and return air also a lifting shaft. piston wind effect caused by frequent operation of large efficient hoisting cages will disturb normal flow airflow transport lane connected to affect underground ventilation effect. Therefore, based on SST k-ω turbulence model, this paper uses dynamic mesh simulate air-fluid cage running verifies simulation data th...

The experimental study of heat and mass transfer in the atmosphere a skip shaft Gypsum mine was carried out during summer winter seasons. air flow overturning observed season due to ingress cold heavy from surface into space. To analyze this phenomenon, computational fluid dynamics (CFD) model processes developed, considering vertical temperature gradient, roughness walls, exchange with lining....

The behavior of rope-guided conveyances is so complicated that the rope-guided hoisting system hasn't been understood thoroughly so far. In this paper, with user-defined functions loaded, ANSYS FLUENT 14.5 was employed to simulate lateral motion of rope-guided conveyances in two typical kinds of shaft layouts. With rope-guided mine elevator and mine cages taken into account, results show that t...
