End-to-End Digital Ore Flow Accounting: From the Block to the Crusher

Obtaining reliable, end-to-end data on ore flow is a critical function for any mineral resource company. This data underpins key business decisions, including the valuation of mineral reserves by site and deposit, total extraction volumes and grades, potential in-situ losses during mining and re-evaluation, and the actual availability of ore for downstream processing.

However, traditional paper-based record-keeping systems fall short of establishing a dependable link between mining operations and processing plants—often at a significant financial cost.

How Ore Flow Is Currently Tracked

Ore flow accounting is performed across multiple operational stages, including:

  • appraising explored and newly discovered resources;
  • estimating reserves prior to extraction;
  • adjusting for losses incurred during haulage and handling;
  • assessing ore prepared for blasting and fragmentation, among others.

In practice, the same data points are often recorded manually in several separate paper logs—starting from when a loaded haul truck leaves the pit, all the way through to ore discharge at the crusher.

This fragmented manual approach creates significant room for error. For example, one operator may enter a given value in their log, while another records a slightly different figure for the same event. The result is a set of mismatched, inconsistent readings across the workflow, with no clear chain of custody or traceability for the data.

For example, consider the following scenario:

  • A mine surveyor at the pit records in a paper log that a haul truck carried 42 tons of ore from Block 7, based on the excavator's onboard scale.
  • The dispatcher at the plant gate logs the same haul but reads 43.5 tons on the weighbridge—because the truck entered with its body raised.
  • The driver, in turn, enters 40 tons on the waybill to comply with axle load limits.
  • By the end of the shift, the accounting department is left balancing three different figures for a single load.
  • Over the course of a month, this discrepancy accumulates to 3–5%, making it impossible to pinpoint exactly where the shortfall occurred.

Accounting with eLog logsheet.ai

An electronic logbook helps eliminate inaccuracies and makes the entire accounting process fully traceable. It is presented as a single-page form with clearly labeled fields for data entry.


How does logsheet.ai's digital log sheet differ from traditional paper ones?

  • You can track data seamlessly from the block to the crusher;
  • Data reconciliation between ore transfer points is performed automatically, and any discrepancy at any stage is immediately flagged in the system;
  • All data is available for viewing in real time;
  • Disputes are minimized—for instance, when one reading shows 42 tons and another shows 43.5;
  • The ability to generate a production report "on the fly" directly from the log data.


How to Implement Electronic Accounting

The process takes no more than three days, after which you receive a fully operational system tailored to your quarry's specific needs:

  • Log setup – using ready-made log sheet templates and accounting for parameters such as blocks, equipment, and warehouse.
  • Employee training – instruction on working with reports on tablets, which can be taken directly to the measurement site.
  • A trial shift – to verify the operation.

This way, the company transitions from relying on average indicators to actual, real-world data, enabling accurate supply planning, precise assessment of subsurface balances, and increased processing efficiency.

What Is a Production Logbook and Why It Matters for Shift Management

In many factories, the production logbook is one of the most important sources of operational information. It records what happened during a shift: how much was produced, which problems occurred, where downtime appeared, who was responsible, and what should be checked by the next team. At first glance, a production logbook may look like a simple daily record. But in reality, it is much more than that. It is a bridge between operators, shift supervisors, maintenance teams, quality managers, and production leaders. When the logbook is filled in carefully, management can understand what is really happening on the shop floor. When it is incomplete, inconsistent, or difficult to analyze, important signals may be lost. What is usually recorded in a production logbook? A typical production logbook may include: date and shift; production line or equipment; planned production quantity; actual production quantity; downtime events; reasons for downtime; defects or quality issue...

How to Turn Production Logs into Management Dashboards

Image
 Most production teams already collect a lot of information every day. Operators write comments. Shift supervisors record downtime. Quality teams report defects. Maintenance teams add notes about equipment problems. Managers ask for plan vs actual numbers. But in many factories, this information stays scattered. Some of it is written in paper logbooks. Some of it is saved in spreadsheets. Some of it is sent in messages. Some of it stays in people’s memory. The result is simple: the company has production records, but management does not always have clear production visibility. This is where structured production logs can become much more valuable. They can become the foundation for management dashboards. A production log is more than a daily record A production log is often treated as a simple shift document. It records what happened during the day or night shift. It may include production quantity, downtime, defects, equipment status, comments, and responsible people. But when thi...

5 digital platforms to simplify shift handovers on the production floor

Image
In continuous production environments, shift handovers require completing various logs that capture critical process parameters, equipment failures, and operator decisions. To ensure the incoming team can start work immediately without missing any prior incidents or updates, they must review the recorded information from the previous shift. When this process relies on manual paper logs, it consumes valuable time, inevitably delaying the start of core operational duties. However, as digital transformation continues to replace traditional paper-based workflows, shift handovers can now be managed far more efficiently through specialized digital services. These solutions drastically reduce the time spent on documentation while significantly improving transparency and overall process control. Below, we explore some of the most effective tools currently available. logsheet.ai Official website: logsheet.ai Subscription fee: $99 per month, covering a team of up to 30 employees.
