Mar 16, 2018 The rule requires operators of underground coal mines to equip place-changing continuous mining machines with proximity detection systems, which use electronic sensors on both mining machines and miners to detect motion or the location of one object relative to another. Certain operational standards must be met.
Mine operators are increasingly installing these proximity detection systems on mining equipment in surface and underground mines to prevent pinning, crushing, or striking accidents. MSHA Approved Proximity Detection Systems for Use in Underground Coal Mines
Aug 20, 2010 Recently, proximity detection systems have been emerging in the mining industry as a useful tool to predict and prevent collisions between one piece of mobile equipment and another, or between a piece of mobile equipment and a person.
Jun 08, 2018 June 8, 2018. Avoiding collisions on a mine site remains an ongoing challenge for the mining industry. While there are numerous collision management systems available, there is limited ability to confidently prove the accuracy and reliability of these systems in production environments.

Browse Magnetic Proximity Sensors. Emerson is where technology and engineering come together to create solutions for the benefit of our customers, driven without compromise for a world in action.
Proximity Sensor Industries such as mining, quarrying, agriculture and construction use machines and plant equipment, which by their very nature pose a danger if they are not managed safely. Blind spots tend to be much larger on these vehicles and include not only the rear and nearside but also the front, especially with elevated driver ...
It also warns operators when a pedestrian has entered the danger zone and is in close proximity to the vehicle. Sensors on pedestrians and on trackless mining machines (TMMs) underground communicate using Radio Frequency ID (RFID) and on wheeled equipment in surface operations use Global Positioning System (GPS) technology.
An active safety solution Proximity sensors for parking and blind spot detection to avoid collisions Significantly increase operator safety, productivity, and peace of mind with intelligent proximity sensors that detect obstacles behind, alongside, and in front of the vehicle. Systems work on their own or integrate seamlessly with backup camera systems in work trucks, truck
A magnetic proximity sensor consists of a reed switch that is controlled by a magnet. When a magnet mounted on the object under test nears the reed switch, the switch closes. Magnetic proximity sensors are EMI immune. They also are not affected by contamination like oil and dust. RFID. RFID sensor systems pass data from tagged objects to RFID ...
