摘　　要：针对来叶沟矿6201工作面浅埋藏、大漏风火区范围广、启封易复燃等难题,设计并实施了均压防灭火系统,在均压过程中进行了风压动态调节,实现了工作面需风量和配风量、采空区内外风压的动态平衡。应用表明,均压防灭火技术能降低地面漏风压差,减少采空区漏风量,达到抑制火区发展直至熄灭火区的目的。Pressure balance fire prevention and control system is designed and applied in #6201 face of Laiyegou Coal Mine in a hope to solve the tough problem of shallow and wide spread fire zone which is prone to revival when the fire zone is reopened.Air pressure regulation in dynamic mode is adopted in the process of air balancing.In this way,a dynamic balance is realized between the face ventilation requirement and air supply as well as the air pressures in and outside the gob area.Actual application of this technology indicates that the pressure balance fire prevention and control technology reduces ground air leakage pressure difference and reduces air leakage into gob areas.This helps greatly to control the development of fire zones and finally reach the target to put out the fire.
