A gas detector calibration schedule should match the detector’s use, the mine’s applicable requirements, and the manufacturer’s instructions. There is no single interval that applies to every fixed, machine-mounted, and portable detector. For example, U.S. regulations require certain methane monitors used on underground coal mining equipment to be calibrated with a known air-methane mixture at …Read More
Two way radio communication devices are mine-ready when they suit the mine’s environment and work reliably with its communication system. A rugged handheld radio alone may not provide coverage underground: the radio, its programmed settings, and the mine’s supporting infrastructure must work together. That distinction matters when comparing radios for crews who work around machinery, …Read More
Here at Becker Wholesale Mine Supply, we support fixed gas monitors in underground mines, and one complaint comes up more than any other. “The CO channel keeps alarming, but the handheld reads zero.” We take that call seriously every time. A monitor that alarms for no reason gets ignored, and a crew that has started …Read More
A gas alarm only matters if the miners and supervisors understand what is happening when it goes off and how to react. Gas leakage sensors may help identify dangerous situations in a mine, but a safe reaction depends on effective alarm systems, reliable communication methods, knowledgeable decision-makers, and an emergency response plan designed specifically for …Read More
Radios for miners must fit the mine’s communication network, working conditions, and applicable safety requirements. A durable handset matters, but underground coverage and a dependable connection to the surface depend on the system around it. At Becker Wholesale Mine Supply, our mining communication offerings include handheld radios and VHF and UHF systems. Here is what …Read More
Mining atmospheres can change quickly. Ventilation shifts, geological conditions, blasting, diesel equipment, and active mining processes can introduce hazardous gases or affect oxygen levels. A reliable gas sensor detector gives mine personnel an earlier indication that atmospheric conditions are moving outside acceptable limits. At Becker Wholesale Mine Supply, we provide gas monitoring solutions designed around …Read More
Reliable communication underground is harder than it looks. Rock, changing tunnel geometry, equipment, distance, and branching entries can all interfere with ordinary radio coverage. A radio that works clearly near the portal may become unreliable once a crew moves deeper underground or around several turns. A tunnel radio leaky feeder system addresses that problem by …Read More
Gas conditions underground can change quickly. Ventilation shifts, blasting, diesel equipment, geological conditions, and work in confined or poorly ventilated areas can all affect the atmosphere miners depend on. An underground gas detector gives mine personnel a way to identify dangerous changes before workers have to rely on symptoms, smell, or visible warning signs. Modern …Read More
A tunnel radio system has to do something ordinary wireless networks struggle with: maintain dependable communication through long, confined spaces surrounded by rock, concrete, steel, equipment, and changing underground conditions. That makes an upgrade more involved than replacing an old radio or installing a stronger amplifier. The entire communication path matters—from the base equipment and …Read More
A gas detection sensor can give mine personnel an early warning when the atmosphere begins moving toward unsafe conditions. In underground and surface mining, that warning matters because dangerous gases may be invisible, difficult to detect without instrumentation, or capable of creating both immediate and long-term hazards. The right monitoring setup depends on more than …Read More
