6 FAQs about [Qianliu core drilling rig spacing]

Which jig is best for surface drilling?

This requires longer core jigs to be used particularly for surface drilling. Relying on the orimark drawn on the surface (along hole length) of the core for accuracy. The orimark drawn on the core cross-section is often more accurate. Acceptable deviation for a driller’s mark from the drawn line is about 10-15 degrees.

What are the basic methods for engineering geology core logging?

This chapter describes the basic methods for engineering geology core logging and provides examples and instructions pertaining to format, descriptive data, and techniques; procedures for working with drillers to obtain the best data; caring for recovered core; and water testing in drill holes.

What is core drilling in geotechnical work?

The basic objective of core drilling in geotechnical work is to document, classify and analyze the rock mass conditions in terms of their suitability for various geotechnical projects as described above.

How is the estimated quantity of drilling determined?

The estimated quantity is determined by considering total linear feet (meters) of drilling, project design schedule, and estimated linear feet (meters) of drilling per rig day accounting for weather, expected drilling difficulty, holidays, etc. that would affect contractor productivity.

What aiming stakes should a drill rig use?

Drillers should use aiming stakes set by the geologist or survey crew for the specified bearing of the drill hole. The rig must be anchored properly so that it will not shift. If stakes have been removed or knocked over, they should be replaced by the geologist. Also, drillers must ensure the hole is drilled at the designated angle.
