The Use of a Decline at Mt. Windarra for Mine Access and Haulage

A system of decline mine entries and ore haulages has been designed for the Mt. Windarra mine. This choice was controlled by the nature of the ore- bodies, the mining method chosen and the capital cost of development re- quired for production. Mine entries are being driven 4 metres high and 5.5 metres wide and decline at 11%, to accommodate diesel haulage vehicles of 35 tonnes capacity. The.Mount Windarra haulage system and the design parameters used in its selection and design are discussed, and general design and selection parameters are proposed.
