Keyword:  自然发火气压计通风系统大面积火区采空区检测火区漏风通道风压调节技术新技术易自燃;
Abstract: 本文介绍了白洞矿为治理大面积火区和组织安全生产所采用的一套新技术、新工艺:用精密气压计测定点压能;用计算机解算网路;用压能图描述矿井通风网路,改造通风系统,降低矿井负压;用 SF6示踪技术检测火区漏风通道;采用了以风压调节技术为主的综合防治自然发火的工艺系统。风压调节以火下盘区进风系统能位为基础,实施了双侧调压,井下火区外围密闭采用以升压气室为主要措施,予以升压。回采工作面采用局部升压系统,在火区上部进风侧不易自燃的落煤采空区建立降压系统,有效地实现了火区漏风系统的均压调节。
