6 FAQs about [Operation of the driver who converted the excavator to a down-the-hole drill]

Why is drilling a pilot hole important?

Drilling the pilot hole is one of the most critical aspects of the HDD process. During pilot hole operations the risk of hydraulic fracture and inadvertent returns (frac outs) is highest because of the small annulus between the drill pipe and hole wall.

How to drill a hole with a drill bit?

Specific operation method: whenever drilling begins, the operator must swing the drilling tools gradually to the bottom of the hole. When the frequency down the hole reaches 700~900 times/min and the pressure of the drilling tool on the drill bit reaches about 3kN, it can be the best impact speed.

How do drill rigs work?

Conventional drilling rigs use the power of an electric motor or a diesel engine, which is transmitted to the turntable through the operating system to drive the drill bit connected to the drill rod to grind and cut the rock to achieve the purpose of drilling. This kind of drill first solves the ground power.

How does a pilot hole work?

In general terms, the pilot hole is advanced with a Bottom Hole Assembly (BHA) consisting of a drill bit attached to either a jetting assembly (soil) or a mud motor (rock). The jetting assembly or mud motor is attached to a non-magnetic drill collar (monel) that houses the downhole steering probe.

What causes a failed drill?

Poor drilling fluid properties can in some cases lead to a failed drill. Where HDD profiles pass through high plasticity clay soils, the soil cuttings can tend to stick together forming large particles that continue to grow until they eventually plug the hole and cause drilling fluid returns to cease.

How does a jack hammer drill work?

It describes the working principles of jack hammer drills, which use compressed air to power a hammer that rapidly pounds a drill bit into rock. It also discusses down-the-hole drilling where the hammer is located directly behind the drill bit to allow for deeper percussion drilling without energy loss through joints.
