6 FAQs about [Patent for automatic hole alignment of down-the-hole drilling rig]

What is an automatic hole positioning and alignment system?

This work describes an automatic hole positioning and alignment system developed for drill rigs. The novelty of the solution is in the surface drilling application and the versatility of a typical drill boom. The system has been tested both in a simulated and a prototype environment.

Why do drill rigs have automatic positioning?

Automatic positioning makes it possible to operate one or more drill rigs more conveniently from a remote control station. The automatic mode is also an enabler technology for autonomous drill rigs. Remote operation and autonomy minimize the need for human intervention and presence at the work site.

How is a drill hole determined?

A drill hole is determined by its starting point on the rock surface, alignment, and depth, as defined in a drilling plan. Prior to actual drilling, the drilling boom must be correctly placed to achieve desired position and alignment of the hole, see Figure 2. Positioning of a drill hole has to be done with a centimeter level accuracy.

What is a drill rig control system?

The drill rig control system is a complex distributed system. Development and integration of a new feature into a distributed control system is challenging with regard to development time and performance verification. The algorithms developed herein were complicated, making these challenges even harder.

What is a surface drill rig?

A modern surface drill rig. According to its name, the method involves drilling holes into rock for charging of explosives and consequently detonating the explosives to fracture and move the rock mass. In open pit mines, quarries and construction sites, the holes are drilled using surface drill rigs, see Figure 1 for an example.

How does a drill rig work?

From the user control commands, the control system of the drill rig forms control signals to the hydraulic valves regulating the oil flow to the boom actuators, which are typically hydraulic cylinders. In the direct control mode, each valve and actuator is controlled individually.
