Newmarket Gold has designed their own drone to inspect open stopes for misfires and to map the surrounding walls inside a mine . Ion Hann , Mine Manager of the Fosterville Gold Mine , said that the mine had already been built and developed last year and is providing remarkable advances in mining today . They hope to reach the stage where drones enter the mining industry as a standard for emergency responses , which includes search and rescue scenarios underground . There are numerous possibilities of this type of technology being introduced in the mining

industry . It can be used to aid with operator training during field work , where a live feed can be sent to the trainer while operator plans a heading . Hann commented that their ultimate goal is to get the drones into an autonomous state so the risks of site inspections and re-entries would lessen as operators would be able to do it on the surface .
