poraukset

Poraukset is the Finnish term for the process of drilling holes in materials or rock. It is used across engineering, construction, mining, and geotechnical surveying to create holes, obtain samples, or install equipment. The word comes from the verb porata (to drill) with the noun-forming suffix -us, and poraukset can refer to both the act of drilling and the resulting holes.

In manufacturing and construction, poraukset describes operations that produce holes for fasteners, fittings, cables, or passageways. In geological and mining contexts, poraukset refers to boreholes drilled to collect samples, study rock properties, or place instrumentation. Core drilling, often called ydinin poraus or core drilling in Finnish sources, is a specific poraus method that preserves a cylindrical sample for laboratory analysis. Rotary and percussion drilling are other common approaches, chosen according to rock hardness, hole size, and project goals.

Equipment used in poraukset includes drills, drill rigs, and bits designed for metal, wood, or rock. Core barrels, casings, and drilling fluids help stabilize holes and manage cuttings. Downhole instrumentation, ventilation, and dust control are frequently employed to ensure safety and data quality. Environmental considerations, such as site restoration and spill prevention, are an important part of planning and execution.

Poraukset are central to resource exploration, foundation design, and infrastructure development. Information obtained from boreholes informs geological models, structural calculations, and risk assessments. See also poraus, ydinporaus, and borehole engineering.
