Method for prevention and control of spontaneous

To detect directly and find out accurate location of the concealed coal seam fires with non-contactable detection methods, such as detecting the heat and gases released from fires, is a difficult task worldwide and has not been solved yet. There are two kinds of detection methods. One is indirect geophysical prospecting, such as detecting radon gas; another one is to directly detect the heatget price

Gas detector Wikipedia

History. Gas leak detection methods became a concern after the effects of harmful gases on human health were discovered. Before modern electronic sensors, early detection methods relied on less precise detectors.Through the 19th and early 20th centuries, coal miners would bring canaries down to the tunnels with them as an early detection system against life-threatening gases such as carbonget price

Seismometer Wikipedia

A seismometer is an instrument that responds to ground motions, such as caused by earthquakes, While not sensitive enough to detect distant earthquakes, this instrument could indicate the direction of the pressure waves and thus help find the epicenter of a local quake. Such instruments were useful in the analysis of the 1906 San Francisco earthquake. Further analysis was performed in theget price
