Hoist Signaling Monitor and Display System.
NTIS: PB/82-198557 :93 pages
This report documents the work performed and the results obtained under a contract that included a mine and manufacturer survey to determine the functional requirements, problem areas, and state of the art of shaft communications. An interest in improved hoist communications was noted during the survey; areas of particular concern were increasing the reliability and decreasing the required maintenance. The manually operated bell-horn system of signaling the hoistroom was also deemed confusing and could result in risks of hazardous actions and inefficient operation. Several designs have been conceptually developed that include environmental protection of cage-mounted communication equipment, an on-board charging system to reduce battery handling, a level-to-hoistroom request display, and a monitoring system. The designs are configured to allow their simple adaptation into existing commerical or mine-constructed communication networks.
