The purpose of this research is to investigate the factors which affect the performance of the loading and hauling equipment at Skorpion zinc mine, Na-mibia and also to find possible solutions to eliminate them, so that the weekly Zinc Oxide and ex-pit waste tonnages required could be produced. WebThis software is capable of simulating any number of shovels (cyclic loading machines) and trucks working together as well as providing a solution to the problem of optimum combination of trucks and shovels using a mixed-size You can calculate cycle time with this simple formula: Cycle time (CT) = Net Production Time (NPT) / Number of Units made (U). Although, dump trucks an haul at a higher rate, technically a fleet with a sufficiently high number of 10-wheel trucks should be able to haul at the same rate. A well-organized fleet management in surface mining is required in order to maximize truck per shovel Match Factors. This is due to the high demand of Zinc on the market. To calculate the cycle time we need to write a simple formula which is, Cycle Time = End Date Start Date.

However, practically the fleet size is limited by many constraints such as cycle distance, cycle time and hauling conditions. Understand the market a better understanding of market needs will reduce cycle time and produce the right quantity. STEPS: Firstly, select the cell where we want to get the cycle time. WebWhat is the impact of poor haul truck cycle time performance? The most common method currently used is computer simulation. You can calculate cycle time with this simple formula: Cycle time (CT) = Net Production Time (NPT) / Number of Units made (U) Here, net production time is the total duration of your production process (or service delivery process) in seconds, minutes, hours, or days. The paper describes the implementation of regression and NN modelling. Continuous capacity is determined first and then discounted for production utilisation later. Truck cycle times at a large open pit mine are estimated using computer simulation, artificial NNs, and MRs. Whats the difference between cycle time. So to calculate the cycle time, the time taken to knit the sweaters: Total number of hours * Number of Days / The total number of Sweaters knit in that period. You can now calculate takt time to find productivity variance. Identifying where bottlenecks occur before they become a problem, Determining if plants are "over- or under-trucked", and make adjustments to improve dispatch order efficiency and throughput, Identifying high-performing plants, truckers, and job sites to create best practices. Basic cycle time = 0.45 to 0.55-min (larger machines = longer basic cycle time), loader cycle time (min)] x loader bucket volume =, View For example, time to cook a meal, etc. It take longer to fill up a 777 Heavy Hauler then a Dump Truck. using this Widget, you can use one of the following routes: ClickUp assumes the first status in Active as Not Started and any, in the Active status group as the start of cycle time, : pick a time range and set the frequency of the cycle time graph, : select the number of days that must appear as the average for each. A WIP limit will set a cap on the number of tasks a team can take up. For example, grade = 10% and rolling resistance = 2%, then Total resistance = 10% + 2% = 12%, then draw a line from a total resistance of 12% to where it intercepts the dotted line for the loaded truck weight, illustrated in red in Figure 3.
