Considerations to Make When Selecting Underground Drilling Equipment

Although underground diamond drilling is comparable to surface drilling, there are significant distinctions which must be taken into account. When selecting your drilling equipment, these distinctions may be important.

Distinctive goals

Since you don't want to delay the extraction phase of the process, underground drilling entails definition drilling as well as the emphasis is on output and speed. Obtaining the highest level of penetration is crucial given this goal. A core bit with excellent speed of rotation and great rock cutting capabilities might offer a higher penetration rate.

Comparing known and unknown ground

Since most mines are already operation for a while, it will be clear what kind of rock is present. There will be several holes, so there won't be many surprises and the stuff will realize what to expect. Drillers can concentrate on bits which have been produced for particular ground types rather than having to restrict their options to core bits which are suited for a wider range of ground. Furthermore, since you are aware of the kind of ground, you could choose a higher crown to decrease the frequency with which you must change the bit.

Hole depths in bores

The majority of the time, while drilling underground, the holes are less deep, say 200 meters as opposed to 1,000 meters. Drillers may decide to use conventional drilling techniques instead of wireline drilling techniques as a result of this. A higher rate of penetration may be achieved by using core bits with thinner kerfs than those used in conventional drilling.

A borehole's direction

The borehole's direction might be down, up, or inclined while drilling underground. You might need to choose a distinct matrix for the core bit as a result of these various directions. It may be necessary to employ a different matrix and drill a series higher while drilling an up hole under certain drilling circumstances.

Drill rigs with less power

Drill rigs are often smaller and less potent in underground drilling since there is less room for them. You require a core bit with a softer matrix while drilling with such a low-powered rig, particularly in an up hole. Also when utilizing equipment which can't supply you with the necessary feed pressure, the core bit will be able to remain sharp, cut well, and deliver a decent penetration rate thanks to the softer matrix's diamonds, which are easily exposed.

Note

We all understand that selecting drilling equipment is probably the most crucial choice which will significantly affect how well you drill. While drilling underground, there are additional crucial aspects to take into account besides the type of ground.
