The use of sensors designed for gas detection in mines has developed from the miner’s canary to infrared sensors A Miner’s Canary The canary Serinus canaria was commonly used by miners to alert them of the presence of toxic vapors such as the odorless carbon monoxide in hazardous areas of underground mining pits

While sensors have replaced canaries and mice alerting workers when air quality conditions are dangerous mines remain an extremely hazardous environment in addition to harmful and explosive gases particles that are a result of coal mining for example have resulted in miners developing black lung aka pneumoconiosis This occupational lung

Specifically NIOSH has reviewed existing sensors and communications network systems used in US underground coal mines to determine whether they are capable of supporting IIoT systems The results show that about 40 percent of the installed postaccident communication systems as of 2014 require minimal or no modification to support IIoT

The resultant gas is present both as liberated gas in fissures and as absorbed gas on the inner surface of the coal During mining operations the mine gas is released causing a real fire and explosive risk The main constituents of Mine gas are Oxygen O 2 Nitrogen N 2 Carbon Dioxide CO s and CH 4 If blasting operations are used in

City sensors are to be found in detection equipment used in the world’s main coal mining regions The top four regions are China which in 2011 accounted for just under 50 of world coal production the USA with a 14 share India which accounts for 6 and Europe 4

May 04 2020 · The NIOSH Mining Program is working to improve the ability to detect and respond to developing fires using a multifaceted approach that involves atmospheric monitoring of targeted mine locations This approach seeks to 1 improve the gas and smoke sensors used in an atmospheric monitoring system AMS for fire detection and hazard analysis 2 upgrade mine ventilation

Apart from these applications tilt sensors are also essential in industrial machine automation Tilt sensors and vehicles used in construction Industrial machines such as those used in construction mining and other similar fields also use tilt sensors for enhanced safety An illustrative example is to prevent heavy equipment from going off

mounted methane monitors currently used in underground coal mines rely on catalytic heat of combustion sensors As a comparison although not currently approved for use on underground mining equipment instruments with infrared sensors are evaluated in this study Potential advantages of using infrared sensors

Mar 07 2018 · Infrared sensors provide some advantages over the conventional heat of combustion sensors that are generally used for mining applications As methane absorbs infrared light very strongly at characteristic wavelengths infrared sensors are usually used in other areas where methane detection is required

Dec 31 2019 · British legislation officially ordered miners to replace canaries with electronic carbon monoxide sensors on still in use in Britain’s coal mines Coal miners face many constant dangers

The resultant gas is present both as liberated gas in fissures and as absorbed gas on the inner surface of the coal During mining operations the mine gas is released causing a real fire and explosive risk The main constituents of Mine gas are Oxygen O 2 Nitrogen N 2 Carbon Dioxide CO s and CH 4 If blasting operations are used in

Intelligent mining operation needs meaningful information From accurate control of chemical dosage to integrated control of widely dispersed operations on a remote site the right process controls are essential for increasing yield rates and enabling mining companies to stay ahead of the global competition

Underground mines are the alternative to surface mines Surface mines excavate from the top down a method that can become inefficient at depths greater than about 200 feet 60 meters sources Illinois Coal Association De BeersUndergrounds coal mines can drive 2500 feet 750 meters into the Earth and other types even deeper uranium mines can reach 6500 feet or 2 kilometers
