Provix Thermal Imaging For Vision Enhancement on Mine Rescue Vehicles and Heavy Equipment – A Case Study
Navigating heavy equipment in darkness, dust, fog, and steam is a challenging task. Equipment lights can be distorted causing additional visual distraction. Thermal Cameras allow operators to see personnel and hazards, as well as other vehicles and equipment, reducing the likelihood of collision and increasing safety and productivity for everyone.
Visibility is limited during underground operations and, therefore, it is difficult for underground mine rescue vehicles and emergency services to respond quickly.
Bitumen laden oil sands are recovered using heavy equipment during surface mining operations. During extraction and reclamation, hot water is used to separate the bitumen from the mined material. After the bitumen has been removed, the spent sand is distributed in an environmentally sensitive manner. During the spreading of the spent sand there is a significant amount of steam rising from the piles of reclaimed material. Fog and other environmental conditions compound this problem.
Thermal Cameras for Visibility
Deployment of thermal imaging cameras has increased forward and rearward visibility for the machine operators due to the ability of the thermal camera system to see in the darkness and through the steam. Thermal Imaging cameras provide for enhanced vision in steam, fog, smoke and dark operating conditions.
Providing the operators with visual acuity in darkness or dense steam allows them to confidently move their equipment, knowing that anything with a heat signature will be clearly shown on the monitor. Both personnel and other operating equipment are clearly detected and operators are able to maintain an effective pace.
What will I see?
In certain environmental conditions, the darkness or steam reduces visibility for the underground mine rescue vehicle or dozer operators similar to a fog bank or a white-out in a snow storm.
The deployment of thermal imaging cameras means the mine rescue vehicle/underground ambulance operators are able to respond to an emergency situation much quicker than navigating blind.
Dozer operators are in danger due to deep water forming from ponding coming out of the discharge pipes. Being unable to line up the dozer blade with the spent sand pile can lead to significant impacts on productivity because of reduced operational speeds, as well as cause unsafe operating conditions due to reduced visibility. Tailings pipes, when in use, are warmer than the surrounding terrain and will be clearly identifiable on the LCD monitor or screen in your cab. Other operating heavy equipment and vehicles will be identifiable on screen because of the heat arising from the engine and exhaust. If a vehicle is not operating and has cooled to ambient temperature, it will not be as easily identified.
One of the main hazards in the tailings cells is the presence of holes or ponds caused by the discharge of the tailings materials. Depending on the ambient temperature, the liquid will be easy to differentiate from the surrounding terrain. This is particularly valuable in the dark, when it is often not possible to differentiate between the terrain and the ponds
Provix supplies a system for mine rescue vehicles that includes two thermal cameras, a gas detection system, emergency lights, and a regular backup camera for emergency vehicles. These have been supplied on Miller Technology Mine rescue vehicles/ underground ambulances that are in use at Agnico Eagle and Vale.
Provix supplies two FLIR thermal cameras for dozers that are automatically activated based on the direction of travel and requiring no operator input to display an enhanced image of what is in front or behind the equipment. The camera operates with a relatively narrow field of view, so as to magnify any object detected.
The cameras are connected to a rugged control panel that is directly connected to the vehicle’s power system. The single magnified image from either camera is displayed on a seven-inch waterproof, dustproof monitor that is ergonomically positioned for ease of reference and can be adjusted to suit individual operators sightlines.
At certain oil sands operations the Provix solution has become an standard operating procedure, and tailings equipment do not run without the thermal camera system. The Provix solution has been implemented by all surface oil sands operations in the Fort McMurray area.
