Obtain samples of earth from sidewalls of well boreholes, using electrically exploding devices.

“Obtain samples of earth from sidewalls of well boreholes, using electrically exploding devices.” is a supplemental task performed by Explosives Workers, Ordnance Handling Experts, and Blasters. Among the occupation's 30 rated tasks, workers place it 4th by importance (#27 most important).

This is a single occupation-specific task statement from O*NET. The figures below describe how central the task is to the job and what independent studies measure about AI and this kind of work — not a prediction that the task will be automated.

AI exposure

The OpenAI / Eloundou “GPTs are GPTs” study rates this task E0. No direct exposure — current language models give little or no time savings on this task.

Exposure measures whether a model could meaningfully speed the task up — it is an estimate of overlap with model capabilities, not a measure of whether the work will be done by software. The study's intermediate score (β) for this task is 0.00. Automation potential label: T0.

Other tasks in this occupation

• Examine blast areas to determine amounts and kinds of explosive charges needed and to ensure that safety laws are observed. · importance 4.9
• Tie specified lengths of delaying fuses into patterns in order to time sequences of explosions. · importance 4.7
• Place safety cones around blast areas to alert other workers of danger zones, and signal workers as necessary to ensure that they clear blast sites prior to explosions. · importance 4.6
• Place explosive charges in holes or other spots; then detonate explosives to demolish structures or to loosen, remove, or displace earth, rock, or other materials. · importance 4.6
• Insert, pack, and pour explosives, such as dynamite, ammonium nitrate, black powder, or slurries into blast holes; then shovel drill cuttings, admit water into boreholes, and tamp material to compact charges. · importance 4.6
• Mark patterns, locations, and depths of charge holes for drilling, and issue drilling instructions. · importance 4.5
• Compile and keep gun and explosives records in compliance with local and federal laws. · importance 4.5

• Connect electrical wire to primers, and cover charges or fill blast holes with clay, drill chips, sand, or other material. · importance 4.5
• Lay primacord between rows of charged blast holes, and tie cord into main lines to form blast patterns. · importance 4.4
• Assemble and position equipment, explosives, and blasting caps in holes at specified depths, or load perforating guns or torpedoes with explosives. · importance 4.3
• Verify detonation of charges by observing control panels, or by listening for the sounds of blasts. · importance 4.3
• Move and store inventories of explosives, loaded perforating guns, and other materials, according to established safety procedures. · importance 4.3
• Light fuses, drop detonating devices into wells or boreholes, or activate firing devices with plungers, dials, or buttons, in order to set off single or multiple blasts. · importance 4.2
