摘　　要：针对某矿42402综采工作面在主要通风机负压通风下,工作面采空区及液压支架后方发生火灾的问题,通过现场分析与通风方式及设备布置调整的方案研究,采用风机—风窗联合均压防灭火的措施,实现了工作面两顺槽风量的动态平衡。结果表明:均压通风防灭火技术提升了工作面风流压力,减少了采空区漏风量,遏制了工作面后方火灾的发生。In view of the problem of fire in the goaf and behind the hydraulic support of 42402 fully mechanized working face under the negative pressure ventilation of the main ventilator,the dynamic balance of the air volume in the two parallel grooves of the working face is realized by adopting the measures of fan window combined pressure equalizing fire prevention and extinguishing through the field analysis and the scheme research of ventilation mode and equipment layout adjustment.The results show that the pressure equalizing ventilation technology can increase the air flow pressure in the working face,reduce the air leakage in the goaf and prevent the fire behind the working face.
