Benefits of technology

[0031]In an embodiment of the first aspect, the determined target is to maximise penetration rates whilst minimising wear on the drill arrangement.

Problems solved by technology

In some situations, there may not be enough information at the initial stage for the user to make an appropriate or informed decision in other words once drilling has commenced, the user generally makes appropriate adjustments in order to successfully drill the hole.
Typically, where the user is required to make appropriate adjustments in order to successfully drill a hole, the drilling process may be inefficient, expensive and time consuming.
When preparing the ground for blasting there may be literally hundreds of holes required with drilling, which may take a number of days to drill.
In open pit mining an additional factor is that the surface being drilled may be disturbed or broken, such as from earlier blasting and the subsequent removal of blast material.

Embodiment Construction

[0043]Referring to FIG. 1, there is shown an embodiment of a method for the autonomous drilling of ground holes by a drill rig including a drilling arrangement, comprising the step of: utilising an autonomous drilling procedure to control the drilling arrangement to drill the hole on locating the drill rig in a position where the hole is to be drilled.

[0044]In this embodiment, the drill rig 100 has a frame 112 housing a number of components such as a drill string 102 connected to a drill bit 104, which define at least part of the drilling arrangement. In operation, the drill rig 100 positions the drill arrangement over a surface 116 for drilling into the surface to produce a hole 118. As the person skilled in the art would appreciate, in the context of the present specification the drilling arrangement can include, without limitation, any components which facilitate the drilling of ground holes, including the frame 112, drill string 102, drill bit 104, air or fluid pumps suitable fo...

Abstract

Embodiments include a method for the autonomous drilling of ground holes by a drill rig including a drilling arrangement. The method includes the step of utilising an autonomous drilling procedure to control the drilling arrangement to drill a hole after locating the drill rig in a position where the hole is to be drilled.

Description

TECHNICAL FIELD[0001]This invention relates to a method for the autonomous drilling of ground holes and, particularly, although not exclusively, to the autonomous drilling of ground holes for the purposes of exploration, mining and / or construction. In particular, the invention relates to the autonomous drilling of ground holes which are used for subsequent blasting.BACKGROUND[0002]Typically, ground holes are drilled by drill rigs in order to produce a hole for use in mining or construction. In some instances, these holes are drilled by a drill rig controlled by a user who plans and executes the drilling process.[0003]The operation of a drill rig requires the consideration of many variables before the user can successfully initiate and complete the drilling operation. These variables include ground or surface conditions, the geological status of the area, environmental conditions, the intended purpose of the hole and the inherent limitations of the drilling equipment. In some situati...
