Research on Temperature Variation during Coal and Gas Outbursts: Implications for Outburst Prediction in Coal Mines [PDF]
Sensors, 2020 Coal and gas outbursts are among the most severe disasters threatening the safety of coal mines around the world. They are dynamic phenomena characterized by large quantities of coal and gas ejected from working faces within a short time. Numerous researchers have conducted studies on outburst prediction, and a variety of indices have been developed to
