Abstract: Based on the existing calculation and prediction of gas emission in coal mine exposure roadway, through the calculation and analysis of the massive historical data from environmental monitoring in underground coal mine, we establish the relationship model between the gas emission from the exposed roadway and the underground environment monitoring parameters. and realize the gas emission amount of underground exposed roadway in coal mine through the real-time data, it is more real-time, precise, continuous and maneuverable for the calculation of gas emission from exposure roadway of underground coal mine.
