6 FAQs about [Down-the-hole drill knowledge database]
What is a down-the-hole drill?
A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud). The DTH hammer is one of the fastest ways to drill hard rock.
What is down-the-hole (DTH) drilling?
Down-the-hole (DTH) drilling has made it easier for contractors to drill wells faster and more efficiently, and to transition from dirt boring to rock boring just by adding a compressor and hammer to the drill bit.
What are the advantages of using down-the-hole drilling tools?
The advantages of using down-the-hole drilling tools are numerous. They offer faster penetration rates and lower energy consumption compared to other methods, making them ideal for large-scale projects. Additionally, DTH drills are versatile and can be used in a wide range of geological formations, from soft soil to hard rock.
Why is a drilling system not used on every drill hole?
The system is operated by a geophysical contractor and the procedure requires cooperation from the drill operators because some of the drilling equipment usually stays in the hole to keep it open. This adds to the expense of doing downhole surveys, which is why they are not typically used on every drill hole.
How can geophysical data be collected from a drill hole?
A string of different probes can be connected to collect more than one type of geophysical information. This data not only provides information about the rocks directly intersected by the drill but can shed light on the rocks up to a few hundred meters around the hole, potentially identifying ore zones that were narrowly missed by the drill hole.
What is a downhole geophysical survey?
Schematic drawing of a down-hole geophysical survey (Image: USGS) Downhole, or borehole, geophysical surveys measure the physical properties of rocks along a subsurface drill hole. Explorers use drill holes to collect core or rock chips, to ‘map’ the rock types down the hole and often send rock chip samples for geochemical analysis.
