Abstract

In the mine pit using the "U" ventilation systems, there is serious gas accumulating phenomenon nearby upper corner. If not effectively in time, the serious coal mine security accident will exist because of the gas ultra to limit. Through analysis to the gas accumulation reason and the distribution rule nearby upper corner, the situation is understood that the wind speed is extremely low near upper corner region and some parts is at eddy flow status; Using the practical and economical real-time monitoring system, accumulative gas can be scattered through the air flow perturbation of hydraulic blower. This method could reduce partial gas concentration of upper corner in order to meet the coal mine security production requirements
