Effect of cage movement on the aerodynamic resistance of mine shafts
Abstract
It is known that the movement of vessels (cages and skips) in mine shafts increases resistance. According to A. M. Karpov, the resistance increases up to 10% during medium intensity of operation and up to 25% during intensive operation, when increased turbulence of the flow persists even during short pauses. In narrow shafts, the resistance can increase up to 50%.
