| الوصف: | If the safe concentration of gas in coal mine exceeds the upper limit, it will bring great risks to coal mine production. Therefore, it is of great significance to study the distribution law of gas concentration on coal face. This paper established the layout plan of gas sensor, measured the gas concentration of each observation point under the wind speed of 3m/s, established the trend surface model of first order to fifth order, and solved the trend surface equation of each order, obtained the best trend surface equation through a variety of testing methods, and studied the gas distribution and migration rules in detail. |
