Rock Drill Test Report

The laboratory determination of intact rock strength is accomplished by the following tests: point load index, unconfined compression, triaxial compression, Brazilian test, and direct shear. The uniaxial (or unconfined) compression test provides the general. . The stiffness of rocks is represented by an equivalent elastic modulus at small- to intermediate-strains. . Note: *Routine rock test procedure described in this manual . The evaluation of rock durability becomes an issue when the materials are to be subjected to the natural elements, seasonal weather, and repeated cycles of temperature (e.g.,. [pdf]

FAQS about Rock Drill Test Report

How should rock samples be sampled for drillability testing?

Rock sampling for drillability testing should be based on a careful engineering geological mapping. The necessary number of samples is determined by the variation of the rock properties and the rock types at the site. Rock samples to be tested in the laboratory should be representative concerning petrography and mechanical properties.

How do you assess drillability in hard rock conditions?

Several methodologies are available to assess drillability (i.e. rock strength, rock surface hardness, rock brittleness, rock abrasivity or rock petrography). This paper includes a review of the state-of-the-art and discussion of relevant parameters that involves drillability assessments in hard rock conditions.

How many drill holes should be placed in a rock sample?

The number and placement of the drill holes is determined by the heterogenity of the rock. The drill spots should be placed in soft and hard layers according to a visual inspection of the rock. E.g. 60% hard and 40% soft layers in a sample would result in 3 holes in the hard layer(s) and 2 holes in the soft layer(s).

Does drillability predict geological influences in hard rock drill and blast tunnelling?

Drillability predicti on – geological influences in hard rock drill and blast tunnelling. Geol Rundsch (1997) 86: 426-438. Thuro, K., Plininger, R.J. (1999).

Where can I find a book on rock drillability?

Rock Drillability Stud y. Helsinki University of Technology, Department of Mining and Metallurgy. Laboratory of Mining Engineering. ISBN 951-753-591-0. Sandvik Tamrock (1999). Rock Excavation Handbook. Sandvik Tamrock Corporation. Thuro, K. (1997). Drillability predicti on – geological influences in hard rock drill and blast tunnelling.

How do you test a Sievers drill bit?

Clamp the pre-cut Sievers’ specimen to the weight and lower it carefully until it contacts the edge of the drill bit. Verify that the edge is parallel with the test surface and release the lever. Start the rotation and run the test until the drill bit has performed 200 revolutions. Note any remarks regarding the drilling as e.g. jumping or shaking.
