综采工作面加架期间的防灭火技术应用

Application of Fire Prevention and Extinguishing Technology During the Addition Period of Fully Mechanized Mining Face

南庄公司8836综采工作面加架停产期间,有较大可能自然发火隐患。通过采取普瑞特Ⅱ防灭火技术措施实现了进回风隅角及工作面两端封堵隐患漏风通道和工作面支架顶部漏风区域的有效封堵,解决了工作面加架期间采空区漏风问题,消除了加架停产期间自然发火隐患。

During the period when the 8836 fully mechanized mining face of Nanzhuang Company is added frame and stopped production,there is a greater possibility of hidden danger of spontaneous combustion.By adopting PrattⅡfire prevention and extinguishing technical measures,the effective plugging of the air leakage passage at both ends of the intake and return air corner of the working face and the air leakage area at the top of the working face support is realized,the problem of air leakage in the goaf during the addition period of the working face is solved,and the hidden danger of spontaneous combustion during the period of adding frame and stopping production is eliminated.
