It's A Gas

Gas-detection or instrumentation devices that test the air quality of workspaces prevent workers from being canaries in a coal mine. The scope of occupations that use some kind of instrumentation device is broader than one might think, according to Bob Henderson, president of Good for Gas Instrumentation (GfG), an international manufacturer of gas-detection products based in Ann Arbor, Michigan.

Coal Mining Tools

When a miner fills a coal car he hangs his I.D. on the side of the car. When the coal is dumped the miner gets credit for the weight of coal. The photo above shows a wooden tamping tool and a metal needle with a handle.These two instruments were used when a miner had to blast a coal vein to break the coal from the vein. A hole is drilled into the vein of coal. Blasting powder is rolled in a

Coal mine low power laser methane detection and alarm

01.12.2019At present, the portable carrier catalytic methane detection and alarm instrument for coal mine generally has many problems, such as high power consumption, short standby time, low detection accuracy, few parameters and single function, which can not meet the rapid development needs of mine safety. In this paper, a low power portable laser methane detection and alarm instrument based on

Gas Sensing Technology Improves Mine Safety

Methane ignition can trigger the much more dangerous coal dust explosions because the shock wave raises coal dust from the floor of the mine galleries to make an explosive mixture that is highly susceptible to spontaneous combustion. Stink damp, so called because of the rotten egg smell of the hydrogen sulphide gas, can explode and is also very toxic. Carbon monoxide, toxic even at low
