【Abstract】 Mine roadways were classified on the basis of their aerodynamics aging regularities. Through the fitting analysis for the relationship of roadway hectometer resistance with time, the experiential formulas of hectometer ventilation resistance changing of different roadways with time were gained using the statistical analysis method. The research provides an important basis for the precautionary maintenance of roadways and the reliability analysis of mine ventilation systems.更多还原
