How should mining and quarrying businesses plan cover for absence so work does not stop?

The first person in a quarry to notice an absence is the weighbridge clerk. Trucks queue at the weighbridge, the pay-loader idles, and the jaw-crusher hopper runs empty. By 7 am the owner knows that the excavator operator did not come. He is also learning that no one else at the face can move the machine without risk. The aim is a plan that makes that morning cheaper.

Not every absence matters equally. A missing helper at the screening belt slows output slightly. A missing drill operator, shotfirer or excavator operator can stop the day. Sketch a grid. One row per job. Columns for the stand-in, whether he is authorised, and how many days he needs to settle.

Role: excavator operator, bench face.
Primary: ________  First cover: ________  Second cover: ________
Authorised on this machine: yes / no / on trial.
Notice needed to bring cover in: same day / one day / three days.
Role: crusher feeder and control panel operator.
Role: drill rig operator and compressor hand.
Role: dumper or tipper driver on the haul road, with the water-tanker hand for dust suppression.
Role: weighbridge clerk and challan writer.
Role: shotfirer, blast crew and magazine keeper (two named people, always)
Role: mate or section supervisor at the face.

Fill it once. Re-read it every month-end with the pit supervisor. A cover name that has left, moved to the crusher or turned unwilling is the usual hole. The pattern behind this, where a handful of skilled hands carry the whole pit, is described on the mining and quarrying hub.

A quarry that keeps no trained spare is paying for every absence in lost hours. The cheapest bench is a second-skill list. Choose two or three steady machine hands. Ask which of them would like a second machine. Train them on a Sunday or in an idle hour. Give a small skill allowance when a person is certified for a second role, so he sees why the effort pays.

1. 1

   Pick the roles in the cover map marked red

   These are the roles with no authorised stand-in.

2. 2

   Choose candidates by attendance and attitude

   A man who is late three days a week is not a good spare, however skilled. Scan the muster roll for steady names.

3. 3

   Train under a senior operator

   Use a written task list: start-up checks, bucket fill pattern, bench edge distance, shut-down. The senior operator signs each task.

4. 4

   Authorise in writing

   A card or a register entry stating who may run which machine. No card, no cab.

5. 5

   Rotate one shift a month

   A skill not used for three months fades. A single shift on the second machine keeps it live.

Role definitions help here. Read role design for mineral processing companies to see how the tasks of a crusher or plant operator are set down.

• Harvest and sowing weeks, when daily-wage hands return to their villages for a fortnight.
• The days after Holi, Dussehra, Diwali and the local jatra, when returns come in staggered.
• Rain days, when haul roads and benches are unsafe and the whole crew is out together.
• Weekly market days, when part of the labour line leaves early.
• Blast days, when the crew is held back for the clearance period.

Pin these on the site-office wall chart. Two weeks before each, call the spare list. Agree who takes the leave on which date, and who stays. Sites that wait until the muster miss the spare operator, who has already gone home.

Even a good plan meets a sudden absence. A short procedure is worth writing in the muster office. Ask who has not come by 6.15. Check the cover map. Phone the first cover before 6.30. If he cannot come, move the day's loading plan: shift the excavator to stockpile work, run the crusher at lower feed, or swap a dumper for a loader. Do not seat an unauthorised man in the cab to rescue the day. A bucket swung into the bench wall costs more than a lost shift.

Contractor workers are often the first to be missing, because their jamadar reports headcount without names. Insist on a name-wise muster. Seek the contractor's own cover list as a condition of the work order. More on recruiting and managing them is in recruitment for mining contractors, and the attendance side in attendance and leave at granite quarries.

Log each absence by role, day of week and reason: sickness, family, festival, weather, unpaid reason unknown. After three months, look for three things. Which role was uncovered most often? Which day of the week loses most men? Which contractor's gang is missing without notice? Use the answers to pick the next training and the next conversation.
