Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western mining operations. All costs listed are in 2012 US. The key design criteria, operating schedule, equipment, personnel, supply requirements and costs are listed below:
Useful_Key_Performance_Indicators_for_ 5 planner would investigate the failure and identify the categories (there maybe more than one category) that influenced the failures. A pie chart or bar chart of work orders per category each month would be a good way to show this KPI.

Assuming 6 hours to remove and replace the engine (MTTR), Mean Time Between Failures is 150 hours. Like automobiles, most manufacturing equipment will be repaired, rather than replaced after a failure, so Mean Time Between Failures is the more appropriate measurement. What is a Failure? "Failure" can have multiple meanings.

equipment is in an operable and committable state at the point in time when it is needed." This definition includes operable and committable factors that are contributed to the equipment itself, the process being performed, and the surrounding facilities and operations. It has various meanings and ways of being computed depending upon its use.
For equipment that works very few hours per day, the derived equipment lives may be very long and local conditions should be checked for the reasonableness of the estimate. Salvage Value (S) This is defined as the price that equipment can be sold for at the time of its disposal. Used equipment rates vary widely throughout the world.

Downtime can also refer to time when human capital or other assets go down. For instance, if employees are in meetings or unable to perform their work due to another constraint, they are down. This can be equally expensive, and can be the result of another asset ( computer/systems) being down. This is also commonly known as "dead time".
Grader Trick of Trade #1: Use the following formula to prepare estimates of the total time (in hours or minutes) required to complete a grader operation. Total time = (P x D) / (S x E) where— P = number of passes required D = distance traveled in each pass, in miles or feet S = speed of grader, in mph or fpm (multiply mph by 88 to convert to fpm)

operating hours. Key findings • The global mining industry''s open cut equipment productivity (ie annual output / capacity of input) has declined by 20% over the past seven years despite a push for increased output and declining market conditions. • Mining equipment in Australia runs at lower annual outputs than most of its global peers.
The simplest way to calculate OEE is as the ratio of Fully Productive Time to Planned Production Time. ... takes into account all events that stop planned production long enough where it makes sense to track a reason for being down ... Formula: Shift Length − Breaks. Example: 480 minutes − .
requires the equipment to be shut down. A review of production schedules is required. Resources are attached to a specific work schedule. The use of resources is balanced out. In the Execution process, trained, competent personnel carry out the required work.

Aug 02, 2013· So if a machine or system runs 50% effective with 1 operator and becomes 65% effective with 2 operators, the effectiveness goes up 30% (yes, 65 is 30% more than 50.) but its efficiency dropped down to 50%, based on labor! The same goes for yield or more commonly known as quality (basically saleable product). If you are bottling a beverage ...
This paper will discuss the application of OEE to measure effectiveness of mining equipment. It identifies causes of time losses for shovel and truck operations and introduces procedure to record time losses. The procedure to estimate OEE of shovels and trucks has ... Total time 720 hours (720 – 4872) =600 hours
Estimation of Open Cut Mining Recovery and Mining Dilution By Kent Bannister, ARMIT, FAusIMM (CP), CEO Kent Bannister Pty Ltd, (KBPL) Summary Loss and dilution of Mineral Resource grade occurs during mining activities. Mining Recovery and Mining Dilution estimates are a required consideration in the reporting of Ore Reserves for mineral projects.
"How to calculate Overall Equipment Effectiveness (OEE)" This is a primaryimportance topic in the Total Productive Maintenance (TPM) discipline. Before discussing about OEE, let me remind you of some basic principles of TPM. TPM was created originally by Nakajima over 20 years ago, and still considered today the leading Plant

Working hours during the shift is defined as excluding "break time for shift change" and including "break time within shift." The TKPH rating data are applicable in the following situations. Ambient temperature at 38°C (100°F). If revised TKPH at various temperature is needed, please refer to (4) below.
Use this free tracking log created in Excel 2010 to record production downtime for data analysis and report generation to evaluate machine performance by shift, product, process, issue, and seasonality. From this tracking log, you can create more detailed downtime reports that will help identify the reasons for equipment failures in order to implement a more effective preventive maintenance ...
Jul 02, 2019· Depreciation expense is directly tied to the wear and tear on the asset: Unlike other methods, units of production depreciation writes down machinery and equipment based on its usage as opposed to time. This more accurately reflects the declining physical value of the asset.
