摘要

Based on the simulated laboratory experiment of pressure balance for fire extinguishing,the pressure regulating technology was summarized for the fire district in Meiyukou Coal Mine.The technology includes three measures for air pressure regulation,namely applying the pressure regulating chamber to balance the air pressure of fire district,increasing the air pressure of the working face,and filling the ground surface fractures.A good effect was obtained to prevent and extinguish the fire.When the measures fail to increase the pressure of working face or to regulate that of air chamber,the measure to fill the ground surface fractures will play an important role.
