Which type of gas detector sensor is more suitable for mining?
Among all industrial production, mining is undoubtedly the most dangerous. As various drill pipes and underground tunnels extend several miles below the Earth's surface, miners face the danger of rapid gas accumulation, fires, and explosions. Due to these and many other hazards, mining operations need to always be equipped with detection systems to ensure that their area is as safe as possible. Due to the fact that methane is the main gas that can lead to catastrophic events in most cases, special mining and industrial detectors are used to monitor methane leaks. However, to understand which systems are effective in these environments, the following are some other detailed information about their functionality and reliability.
Airborne detector
According to federal regulations, all coal mining enterprises need to have mining detector technology to monitor methane and oxygen levels that may be at dangerously low levels. Therefore, the detection equipment is placed on all drilling equipment and specially calibrated to detect methane levels of 1% or higher, which will trigger an alarm from the detection equipment. Due to the importance of protecting the electronic devices in these detectors from dust, dirt, and vibration, they are equipped with special protective covers to prevent damage.
Portable monitoring
In addition to meeting federal requirements for airborne detection systems, many mining operations also use portable mining detectors to ensure workers are protected from dangerous methane leaks. Due to the small size of these detectors, they can be clipped onto miners' clothes or belts, making hands-free monitoring possible almost anywhere in the mine. Accompanying this, like fixed detectors, portable mining and industrial sensors are equipped with wireless technology, allowing them to send real-time data to monitoring stations and mining safety engineers.
Quick response time
In many mining operations, methane leakage occurs when the shaft is first opened. Therefore, once the drilling operation stops and the equipment is moved to another location, methane will be released through underground cracks or rock wall cracks, leading to dangerous accumulation within a few minutes. Due to the possibility of fire or explosion in these situations, a rapid response time is required once high methane content is detected. For this reason, mining sensor technology not only relies on professional electronic equipment and precise calibration of sensors, but also relies on detectors equipped with various alarm systems. For most detectors, the alarm system includes alarms, flashing lights, and strobe lights, all of which will be useful in emergency situations when the wellbore needs to be emptied.
