As of December 11, 2013, Xinqiao Mining Company successfully concluded the underground anti-wind test conducted under the requirements of the Safety Regulations for Metals, Nonmetal Mines and the Company’s Emergency Rescue Plan for Work Safety Accidents. The anti-wind test, aimed at the use of the main fan MAF-2550 / 1450-1B (No. 1) reverse the wind, that is, the exchange of motor power two-phase contacts, change the motor and fan impeller rotation direction, to. At the same time, by collecting and studying the change of wind resistance value of the main return airway and the contact lane under the condition of the anti-wind, it is necessary to master the main return airway and the contact lane
