  • Description:
    "A hoisting and ore pass research facility was developed at the Spokane Research Center, Washington to assess methods for improving the safety of mine shaft and ore pass vertical movement operations. The technology available, including equipment used and sensor availability were assessed. The performance of hoist control equipment (hoist room controls, motors and gearboxes, and winders) and infrastructure (support frameworks, guides, wire ropes, and skips and cages), conveyance monitoring processes, and elevator control systems were also assessed. The information gathered contributed to the development of a new hoisting and ore pass testing facility, and improvements to the design of monitoring and data collection equipment. Critical hoist operating parameters such as conveyance position, conveyance speed and acceleration, load, rope tension, and shaft guide misalignment could be monitored and assessed. It was also possible to investigate the causes of ore pass blockages and to increase safety by detecting blockages and improving hang up removal methods." - NIOSHTIC-2
