Maximum productivity with maximum safety
The performance of a mine largely depends on the perfor-mance of the shaft hoisting system. The mine shaft with its hoisting equipment can be a bottleneck for the mine's production – a place where maximum transportation of people and material in compliance with the highest safety standards is required. Consequently, the demands placed
Research on operation characteristics of hoisting …
To enhance the operating stability of mine hoisting system and provide guidance for the mining shaft deformation (MSD) monitoring, the operating characteristics of the hoisting conveyance (OCHC) under MSD are studied. Firstly, a simplified finite element model is established for analyzing the guide rail (GR) deformation law under MSD, and the deformation …
Application of dynamic braking to mine hoisting systems
Accidents occurred on counterweighted mine hoisting systems when the mechanical brake failed while the cage was empty. This allowed the counterweight to fall to the bottom of the shaft, causing the cage to overspeed and crash into the headframe. Direct-current hoist motors have the potential for preventing this type of accident by incorporating a passive electrical braking …
