Examples of borehole in a sentence

  • Borehole tensile (axial) displacement initiates before shearing, which occurs at 3 to 4 MPa higher pressure.

  • While in the past extensive research has been conducted on slope stability investigations and analysis, this research consists of field investigations addressing both the characterization and reinforcement of such slope failures.The current research focuses on applying an infrequently-used testing technique comprised of the Borehole Shear Test (BST).

  • RGW1 = Underground mining area water samples, RGW2 = Tap water samples, RGW3 = Mining pond water samples, RGW4 = Borehole water samples, RGW5 = Well water samples.

  • To limit the influence of single drill holes on each estimate, a key field (“MAXKEY”) based on the “BHID” (Borehole Identified), has been used, whereby a maximum number of samples per borehole is set to ensure that more than a single hole is used in each case.
