Accurate drill hole measurements
When planning extraction and making orebody estimates, it is important for the locations of the core sample and potential ore deposit to be precisely determined. When drilling, our measurement team provides fluent drill hole measurements, also for old drill holes if necessary.
Accurate results from deviation surveys
Deviation surveys can accurately determine the course and end point of the drill hole. The deviation survey is usually conducted after the completion of a hole, but with deep or branched holes, the survey can be conducted several times at the desired interval.
Water pressure surveys provide data on rock integrity
Water pressure surveys specify the integrity of the rock to be surveyed. Water pressure surveys provide extra information about the fragmented zones in the bedrock and the scale of such. The measurement findings can be calculated as Lugeons.
Our measurement services also include the locating of boreholes in the earth using a precision GPS device, and the measurement of boreholes’ start azimuth once drilling is complete.
We use this equipment for directional surveys
This device has a mechanical gyroscope that provides location data in relation to the Geographic North Pole. It provides the best possible accuracy of measurement – no other equipment is needed!
Northseeking Gyro is suitable for measuring all kinds of boreholes but it is particularly useful in measuring deep and branched holes.
This electronic gyro device is a good all-round tool for most situations. The device can be practically used for measuring old boreholes without the need for bringing the drill rig to the site. Reflex Gyro is also suitable for measurements in underground mines.
This is an extremely easy-to-use, non-magnetic device for all kinds of measurements. Devico Deviflex is especially handy for shallow holes and daily use.
