| Task | AI exposure |
|---|---|
| Cut slabs of stone into sheets that will be used for floors or counters. Software can plan cut sheets from drawings, saw operation stays physical. | 30% AI helps |
| Mark dimensions or outlines on stone prior to cutting, using rules and chalk lines. AI can read drawings to generate layouts, marking stays manual. | 20% AI helps |
| Locate grain line patterns to determine how rocks will split when cut. Reading grain on physical stone needs trained eyes and hands. | 12% Needs a person |
| Remove pieces of stone from larger masses, using jackhammers, wedges, and other tools. Removing stone with jackhammers and wedges is physical work. | 8% Needs a person |
| Cut grooves along outlines, using chisels. Chiseling grooves along outlines is skilled hands on work. | 6% Needs a person |
| Drill holes along outlines, using jackhammers. Drilling outlines with jackhammers is physical and hazardous. | 5% Needs a person |
| Insert wedges and feathers into holes, and drive wedges with sledgehammers to split stone sections from masses. Driving wedges and feathers into stone is physical hands on work. | 4% Needs a person |
| Drill holes into sides of stones broken from masses, insert dogs or attach slings, and direct removal of stones. Attaching slings and directing lifts needs live physical presence. | 4% Needs a person |
| Set charges of explosives to split rock. Charging explosives is licensed, hazardous, physical work. | 3% Needs a person |

Questions about rock splitters and AI
Will AI replace rock splitters?
Partly. About 1 in 10 of a rock splitter's working hours go to tasks AI can already do, mostly cutting slabs into sheets and marking dimensions on stone. Splitting, drilling, and reading grain stay with people because they need hands on the rock in the quarry.
Which rock splitter tasks is AI taking over?
Cutting slabs into sheets is the most exposed task, with an exposure score of 30, because software can plan sheet layouts from drawings. Marking dimensions and outlines scores 20, since AI can read drawings to generate layouts. The saw operation itself stays physical.
Which rock splitter tasks stay human?
Reading grain lines scores 12 on exposure because it needs trained eyes and hands on physical stone. Removing stone with jackhammers and wedges scores 8, and charging explosives scores 3, since both are physical, hazardous work done on site.
How can rock splitters stay valuable?
Read grain lines on each block before splitting, since that judgment is hardest to automate. Check AI-drafted cut sheets against drawings in AutoCAD before sawing. Log yield and waste per block in Excel to show where cuts lose stone.
