Abstract
Provided is a telerobotic mining device for underground mining, and specifically for stope mining, as well as a method of mining using such a device. The telerobitic mining device is capable of remotely moving about a mine and utilizing drill arms to drill a hole within a chosen rock bed. Explosive placement arms on the telerobot may be utilized to place an explosive within the drilled hole to blast away rock. Control over the device is achieved by way of operational commands that may be wirelessly sent to the device from a command center located outside the mine.
Claims12
A method for shrinkage stoping of an ore body comprising,
- lowering a telerobot onto a loose ore platform within a stope, the loose ore being drawn from the stope from below through at least one drawpoint,
- operating the telerobot on the loose ore platform using a combination of (a) teleoperation by operational commands received over a wireless network from a command centre, and (b) autonomous operation by execution of operational commands stored in a programmable memory of a microcontroller on the telerobot based on predetermined input information,
- moving the telerobot through teleoperation to a position proximate to a rock wall to be blasted,
- sensing the configuration of the rock wall surface using at least one onboard sensor and transmitting the sensed information over the wireless network to the command centre,
- extending a plurality of drill arms from the telerobot through autonomous operation to drill corresponding holes into the rock wall at locations predetermined by a teleoperator based on the sensed information, and
- placing at least one explosive into each hole through autonomous operation,
- moving the telerobot to a safe location away from the rock wall through teleoperation before igniting the explosives.
The use of a telerobot for shrinkage stoping of an ore body comprising,

- placing at least one explosive into each hole through autonomous operation,
- moving the telerobot to a safe location away from the rock wall through teleoperation before igniting the explosives.
