Cameras for mines and tunnels are an essential element of security and safety monitoring. The mining sector presents a number of challenges, from low lighting to connectivity issues in remote areas. These surveillance cameras observe the many processes within the mine and are mostly installed in a permanent, overt manner, with portable covert cameras being used on a temporary basis. IR thermal imaging cameras are often used as they offer the ability to see in dark, foggy or dust filled environments where there are large trucks, cranes, robotics and other moving apparatus that present danger to humans.

Driverless vehicles and Autonomous Drilling Systems that can operate without human intervention allow operations around the clock, enabling minerals to be extracted and processed in shorter time-frames. Real-Time Kinematic GPS (RTK-GPS) is used In underground mines due to a limited range of signal transmission below the surface and lack of satellite coverage in depth. RTK-GPS is used to ensure autonomous vehicles and drilling systems have clear path-tracking and collision avoidance capabilities. GPS-guided drilling operations. GPS provides accurate information to the drill head to control its direction deep within the earth.

Fiber-optic Distributed Temperature Sensing (DTS) systems and pressure gauges enable critical monitoring during exploration and energy production for Enhanced Geothermal Systems (EGS). These sensors can be used to: – Estimate production potential in or between new wells by measuring the distributed temperature and the point pressure, or pressure measured at the bottom of the well. These measurements allow the calculation of reservoir size, flow resistance between wells (if multiple wells are instrumented), well bore damage caused by drilling, effectiveness of the fracturing operations, and well completion. – Monitor surface and subsurface scale buildup and chemical clean-up. Scale, a mineral residue precipitated from geothermal fluid in response to changes in water pressure and temperature, builds up on pipe walls and will, over time, form a thick, insulating layer that limits flow and may block a pipe. Chemicals are injected into the pipe to remove the accumulated scale. By understanding severity of the scaling, operators can better consider what mitigation options are most suitable as well as minimize the use of expensive chemicals. – Provide permanent monitoring of injector and producer wells to allow identification of the specific zones and fractures that produce fluids. – Perform integrity monitoring for casing and tubing leaks to avoid contaminating ground water and subsurface aquifers.

Wind Turbine sensors are used to continually assess acceleration, temperature and vibration. Turbine impact sensors – for monitoring avian and bat collisions Turbine vibration sensors – Vibration sensors provide data that enables predictive maintenance, allowing operators to manage assets at a distance – Turbine – Because of variable wind speeds and frequent braking, the load is never consistent on the turbine, causing a lot of wear on the moving parts. Bearings are the biggest culprit in gearbox failure. When bearings fail, it usually leads to other components, such as gearwheels, breaking down, causing a domino effect of failure across the entire apparatus. One of the biggest issues with regard to bearing failure is lubrication starvation. Vibration sensors can help an operator stay ahead of lubrication issues by detecting subtle friction changes -Blade – Wear and tear on rotor blades come from high winds, lightning, ice, and extreme weather conditions that result in blade imbalance. Over time, these factors lead to cracking and fractures along the edges and pitch system failure. Wireless vibration sensors make it feasible to remotely monitor such conditions, alerting operators to impending failure and maintenance needs without physically accessing the site. These sensors are combined together into one communication channel. Associated KPI’s are considered in the aggregate.
