CPL · Coal Production Hourly Logsheet

Run the pit on this hour’s numbers, not yesterday’s.

CPL replaces the paper logsheet and the spreadsheet behind it. Clerks tap each load in the pit, signal or none. Supervisors and managers see BCM against plan, what is standing, and what is still owed, while there is still shift left to fix it.

CPL on a desktop: the mine manager's board showing plan, actual, variance and achievement for the day, BCM by hour, and the machines stopping production now
CPL on a phone: the shift supervisor's board with shift BCM, plan to now, variance and projected BCM

Screens from CPL, on a sample shift.

The problem

By the time paper reaches the office, the shift is over.

  1. 06:00 to 18:00Loads are tallied on paper in the cab and at the face.
  2. After the shiftThe sheets are collected and typed into a spreadsheet.
  3. Next morningThe office reads what the pit did yesterday.

A machine that stood for three hours is a line in tomorrow’s report. With CPL it is on a screen while it is still standing.

For the manager

See the shift while you can still change it.

  • Plan, actual, variance and achievement for the day, by the hour
  • Coal, waste and rehandle, each against its own plan
  • What is stopping production right now, and for how long
  • What is waiting on you: a day to confirm, a shift to approve
The mine manager's board: plan 10,000 BCM, actual 1,508 BCM, variance and achievement, a BCM-per-hour chart, two machines stopped on engineering faults, and coal and waste against plan

For the clerk

One tap a load. Where the work is.

  • Loads per truck, per hour, against each loading unit and material
  • BCM worked out from the site’s own factors, not by hand
  • The shift’s target is the site’s rate × hours × loading units
  • No signal, no problem: it is saved on the phone and sent later
The hourly logsheet on a desktop: loads per truck for each hour of a day shift, BCM per hour, and the steps to approval
The same logsheet on a phone, with the plus-one button on the hour in progress

For engineering

Machines, downtime and diesel on the same page as production.

  • Availability and utilisation by machine class, from real hour meters
  • Every stop with its cause, its duration and the BCM it cost
  • Diesel issued, litres per machine hour and litres per BCM
  • Closing readings taken at hand-over, so nothing is guessed later
Machines by class with availability, utilisation and BCM per hour; downtime today split into operational and engineering with the estimated loss; diesel issued and litres per machine hour

And the rest

Built for a mine, not adapted to one.

A shift with CPL

From 06:00 to 06:00, hour by hour.

06121800

06:00 to 06:00Day until 18:00, night after

  1. 1

    The shift is already there

    Day runs 06:00 to 18:00 and Night 18:00 to 06:00. Nobody opens a shift: CPL works it out from the clock and the site.

  2. 2

    Each hour is captured as it happens

    One tap a load, against the truck and its loading unit. An hour with nothing in it reads 0 by itself.

  3. 3

    The machines are closed at hand-over

    Closing hour meters are read while the dials still show the shift’s figures, so the next shift starts from a true opening.

  4. 4

    The shift is sent up and approved

    The clerk sends it, a supervisor approves it, and the figures are locked with their history.

  5. 5

    The office already has it

    The shift report, daily tracker and dashboards followed the pit all day. There is nothing left to type.
