6 FAQs about [Digging and converting down-the-hole drilling rig tunnels]

What are tunneling and drilling operations?

Tunneling and drilling operations can be categorized into two main types: (1) operations where excavation is carried out by selectively attacking the rock face, and (2) operations that advance the whole cross section of the excavation simultaneously using a device.

How does a down-the-hole drill work?

In down-the-hole drilling a drill rod is fitted with a hammer at its lower end. The hammer, which is mounted on the drill bit, is activated through the addition of compressed air and driven into the ground – simultaneously rotating and impacting. A flushing current collects the loosened drill cuttings and conveys them upwards.

What is a down-the-hole drilling method?

The video shows the down-the-hole drilling method for very hard soil or rock. A rotary drilling rig, type LB 20, working with down-the-hole hammer inside a casing. A flushing current conveys the loosened drill cuttings upwards and exits at the upper end of the casing.

How is a hole drilled in soft ground?

In soft ground, a hole is drilled by using a drill pipe rotating inside a 'washover pipe'. The washover pipe is periodically advanced to catch up with the drilling assembly. This pipe carries the return mud and cuttings back to the surface, minimizing erosion of the borehole and preventing it from collapsing.

What equipment is used to drill a vertical hole?

To drill a vertically aligned hole, the equipment consists of an orientable whipstock, a directional drilling assembly, and a straight drilling assembly ( Figure 7.9 ). First, the whipstock is lowered into the previously drilled vertical hole and oriented. Then, the directional drilling assembly is lowered.

What is directional drilling?

Directional drilling is a technique in which the drilling assembly is attached to a coiled tubing unit rather than to conventional drill pipe. This method is used in reservoirs where there are open fractures with different reservoir pressures. Recent work has involved the drilling of directional and horizontal holes using this technique.
