Sandvik offers a number of different services where we on demand by you as customer investigate in specific areas to achieve operational improvements and/or other requested needs and ambitions.
Dynamic simulation study
Using Cyber cube software, a mathematical model is developed whereby the dynamic effects of various random operational scenarios can be accounted for and expressed as a potential loss of production or increase in operational cost. Scenarios such as multiple equipment breakdowns occurring
at one time with only one service crew available, could cause a bigger loss in production than a similar amount of breakdowns occurring individually over the duration of a shift, to use one example. Fleet size, crew composition, shift configuration, workshop location influence and the effect of a roaming or static refueling station are typical outcomes requested by customers. Typical trade-off studies such as trucks versus conveyors or Drills versus Drill/Bolter combinations are further examples of customer study requests.
Deliverables
• Sandvik site visit to collect data and define requirements
• Dynamic simulation software program
• Feedback and trade-off results report and spread sheets
• Training session on how to use the model
Production cost/model
A Production Model is a mathematical model of a specific customer operation, conducted by a Sandvik System Engineer to determine individual machine productivity levels achievable and ultimate fleet size requirements within constraints such as: ground conditions, shift structures, operator competence, mine lay-out, tramming distances, dip angles of drives etc.
Deliverables
• Mathematical model in Excel format
• Written feedback report on model findings and influences
• Recommendations on mine lay-out optimization opportunities etc.
• Fleet size and configuration recommendation
• Expected production to be delivered by fleet
• Fleet operating cost
• Mine operating cost related to fleet, including explosives, tyres, operators, diesel etc.
Equipment replacement strategy
The Optimal Replacement Interval study is the analysis of your primary production fleet data over the life of the fleet. The objective is to advice you on the exact and most cost effective time interval to replace an individual piece and/or fleet of mining machinery. The study can be conducted for Drills, Bolters, Loaders, Trucks, Surface Drills, Surface Trucks and Crushers. The study considers cumulative maintenance cost, labor cost, capital cost, productivity and the cost related with the increasing unavailability of a machine within a production section.
Deliverables
• A list of all capital equipment with expected replacement dates
• The production and cost model used to determine the dates
• An mathematical model configured for that specific site that could be used by the customer to continue the study by updating data over time
• Sandvik provides training to the customer’s Asset Management team in the continued use of the model
• A detailed report of the study findings and recommendations
Continuous productivity imporvment (CPI)
Continuous Productivity Improvement is a framework of continuous operational measurements forming trend lines over time, allowing Operations to identify bottlenecks through cross referencing of the measurements and ultimately become pro-active in resolving operational bottlenecks. Sandvik will spend time on site defining the various measures required for optimization, identify the source of measurements to be taken on a monthly basis and configure an analysis model to site specific requirements to deliver data that enables the quick identification and quantification of productivity improvement initiatives available:
Deliverables
• Sandvik team on site will develop and configure the CPI model
• A continuous improvement tool configured for site specific interest
• Training of the customer’s appointed team in the use of the model
• Configuration of the feedback and follow up systems required to ensure projects identified are converted into value
• The Sandvik team will conduct the first CPI study and provide associated feedback meetings, reports and improvement initiative mobilization
• A list of improvement initiatives to be conducted over an agreed period of time
• Periodic (bi-annual for 1 year period) remote review of future CPI results by the Sandvik team as a quality control service to the local CI team
