The right formula for optimal production depends on the correct data

Solutions = timing, weather, proximity + Nexus + experience

Formulas can be “iffy” propositions if the variables are unknown or unattended because x factors have a way of interfering with otherwise sound suppositions, theories and extrapolations. All that is to say, that starting with the correct data and understanding the factors that form the lens through which it can and should analysed is the key to accuracy. It’s often noted that not being able to trust the data is the same as not knowing or having the data. From there, the only reasonable step is to take a long step backwards into the “safe zone” or the safest zone. In other words we retreat well behind the regulatory guidelines because we have no wish (and can’t afford) to cross them. The result? Conservatism which bears conservative yields while the potential yields simply become theoretical or wishful thinking.

Again, data that can be relied upon because of the quality of the measurement tools as well as an understanding of their application is key to achieving optimal results.

One way or another, we need to understand the problem in order to execute a solution

Most of the time there is more than one way to approach a problem however, in our industry we are looking for the best answer. The difference between the best answer and one that is merely correct can be measured in millions of dollars, often more. In order to determine the best solution for a client that was faced with the common challenge of operating optimally in an area bound by regulatory noise restrictions, we needed to outline and test a number of approaches. Importantly, progress had been impeded previously by results that varied. Some of these variations pushed the noise levels outside acceptable dB limits or at least cast doubts over the true number. The critical questions were:

1. What were the sources/causes of said variations?

2. How could they be accurately taken into account when modelling scenarios?

3. Having stabilised the data, what action can be taken post analysis?

In summary, the task was to propose ways in which mining and transport activities could continue at an acceptable level without falling foul of acceptable noise levels throughout the various hours of operation.

Nexus for planning, modelling and analysis

In short, Nexus was made for this type of complex, multi-tiered problem solving. In the scenario faced by our client, a number of factors needed to be considered, all of which were easily and simply accounted for with Nexus’ Integrated Solution. A range of administrative approaches were formulated once levels were accurately captured in real time. Previously, variances outside the allowable levels were caused, or at least contributed to by meteorological

events or naturally-occurring environmental activity; and transport and haulage operations. Nexus enables your site based team to recognise, evaluate and nullify the effects of conditions that may hamper your operations . In this case it was proactively recognised what and how activities needed which resulted in the necessary adjustments to schedules. Again, the aim was to establish and maintain optimal productivity, regardless of the planned activities undertaken.

Finally, as has been previously stated elsewhere, Nexus was set up to gather, record and present facts in a format that is:

1. Easy to collect

2. Easy to collate

3. Simple to interpret

Thanks to the quality of data that was captured and accuracy of the system, a number of alternate plans could be formulated and tested against desired outcomes. These involved:

1. accurately providing situational awareness of near term issues

2. variable proximities between operations and the nearby town, taking into account meteorological conditions

3. adaptive management approaches which were based on both scheduled activities and forecast weather.

The third approach was the one from which the client could secure the best results, all thanks to an integrated system (Nexus) that did not rely solely on weeks or months of readings. Time that could be best spent undertaking core operations as opposed to either operating sub-optimally or not at all.
