Web As the cycle distance increases, the overall productivity decreases (1184 T at 1.6-1.8km) (735 T at 2.9-3.1km) Factors that drive this decrease in Production : A) The increase in cycle distances contribute to increase in cycle time resulting in few load for a given time period. Load Time: This is the calculation of addingthe Excavator Pass Time and the Truck Switch Time in Front of the Excavator to come up with the complete time required for each truck to be loaded. Accurate prediction of cycle times is critical to mine planners as it impacts on production targets and hence, the budgets. But for a brief read-through, lets use Mr. Flintstones. The most common method currently used is computer simulation. Truck Cycle Time, Alternatie Route, Graded Homework Spreadsheet- Raman Rajpal, Unformatted text preview: By R.

This way, you can constantly track how long youre spending to ensure youre not exceeding your average cycle time. WebCosting and hauling rates were computed from data extracted from FMC and Quarry Performance sheets. To calculate all that, Lead Time is used. These factors increase the cycle time of the hauling machine s. Reducing the cycle time would increase equipment effectiveness and mine output. The estimated cycle times by each method are in turn compared to the actual cycle times recorded by a computerized mine monitoring system at What Are The Benefits Of Calculating Cycle Time? Definition Continuous Capacity the continuous passes per hour are determined from swing time and this multiplied by bucket capacity gives the hourly production capacity that would be expected.
