AI Technical Summary

Benefits of technology

The present invention allows for the remote operation of a mining system, without the need for ground support or human activity. This results in significant cost and safety benefits. Additionally, the invention reduces environmental impacts and water consumption. It allows for the expansion of the borehole in targeted directions, improving the overall efficiency of the mining process.

Problems solved by technology

Additionally, for narrow or stringy ore zones, waste may be mined with the ore that is unable to be excavated separately causing dilution to the ore.

Embodiment Construction

[0109]Throughout this specification, unless the context requires otherwise, the word “comprise” or variations such as “comprises” or “comprising”, will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers.

[0110]This invention is a new mining method for extraction of ore wherein it is a “non-entry method” for rock mining. The ore is broken in situ by remotely accessing it through a borehole. The broken ore is then recovered from the borehole using vacuum, venturi, pumping or mechanical methods and processed to remove minerals of value. No personnel are required to be at the mine face in the mining process. This invention is unique in its utilization of boreholes only, to intersect, define, access and extract rock ore bodies.

[0111]Breaking of the ore in situ is achieved by a number of methods that may include mechanical ablation, laser spalling, flame or heat spalling, plasma spalling, water jet a...

Abstract

A method of mining comprising the steps of introducing a mining head into a borehole fracturing the ore with the mining head and extracting the fractured ore through a borehole to a location remote from the mining head.

Description

TECHNICAL FIELD[0001]This invention relates to development of a mining method to access and mine rock mineral deposits. The invention can also be applied to enhance conventional underground and open pit mining methods in certain applications.BACKGROUND ART[0002]The following discussion of the background art is intended to facilitate an understanding of the present invention only. The discussion is not an acknowledgement or admission that any of the material referred to is or was part of the common general knowledge as at the priority date of the application.[0003]Conventional rock mining methods are generally characterised as entry methods in that personnel are required to attend in or near the mining face to facilitate excavation, equipment repair or other works. They are also generally characterised by machinery (mostly diesel or electric powered) that is usually manned, being deployed directly at the rock face to break and load the ore and transport it to a processing facility.
