摘　　要：采用自行设计的采场均压防灭火模型，模拟研究了采场四周无漏风、杜绝地表漏风和气室卸压等几种情况下的火区及火区下采空区内的风压分布．采用风窗－风机升压系统对高压能火区实施均压的措施，能达到火下采空区风压高于火区风压，且均处于正压区段的效果．According to the selfdesigned model of fire prevention and extinction with counter pressure in fire field,air pressure distribution of fire zone and goaf under fire zone without leakage around fire field and in stopping surfae leakage and with pressure reduction airchamber is studied. By adopting practical counter pressure measures in high pressure fire zone with air regulatorfan rising pressure,the effect that air pressure of goaf under fire zone is higher than that of fire zone and both are relatively positive is obtained.
