GENWAL COAL MINE INSTALL PED TO IMPROVE PRODUCTIVITY
MINE: GENWAL
OWNER: GENWAL RESOURCES/ANDALEX RESOURCES
TYPE: COAL
LOCATION: PRICE, UTAH, USA
BACKGROUND
Existing mine communications were via a paging phone system. The limitation of this was getting in touch with people quickly. PED was investigated after other mines in the area (Trail Mountain, Deer Creek, Cyprus Plateau) successfully installed the system and confirmed the benefits gained by genuine mine wide coverage.
COMPOSITION
The transmission system consists of a single transmitter powering a 5km (3 mile) underground loop antenna. 20 BeltPED Personal Receivers initially.
DESCRIPTION
The single underground antenna is installed in the main travelway and parallel heading (drive). The signal radiates off the narrow loop antenna into the longwall panels to achieve mine wide coverage. The transmitter and computer are installed in a manned underground office. The BeltPEDs are primarily utilised by maintenance personnel.
JUSTIFICATION
Genwal justified the system on reduced downtime due to maintenance issues. The system dramatically reduced contact time for key personnel, hence ensuring a high availability of the longwall.
