Research on Calculation of Roadway Friction Resistance of Mine Ventilation
The roadway coefficient of frictional resistance as an important basis for the parameters in the mine ventilation theory, plays an important role to the correlation calculation. Through TIEFA coal and YANGQUAN coal industry group and other mine conducted ventilation resistance measurement, a large number of the data were obtained from coal mine. The roadway can be divided according to the types and shapes of the roadway by using mathematical analysis, preprocessing the data by combining with filtering analysis, and the roadways coefficient of frictional resistance can be calculated by using statistical analysis simulation. The friction resistance variation orderliness can be found in the different roadway. The empirical formula can be obtained that it was carried out tolerance analysis for improving the accuracy and reliability of the coefficient of frictional resistance. In consequence, a brief calculation formula to the mine ventilation resistance and measuring method of the mine ventilation resistance measurement can be advanced. It not only leave out a large of labor force and material resources in the mine ventilation resistance measurement, but also it has practical significance to the management of mine ventilation technology in the future.
