地面裂隙带漏风防治方法

Ground Fissure Zone Air Leakage Prevention and Treatment

在矿井中,绝大部分自燃火灾由采空区漏风引起的。针对采空区漏风风流的状况,应用不同的技术和方法进行检测,可以估计出矿井的漏风通路,以判断漏风的方向,为防止采空区煤炭自燃,保证采煤工作面安全生产提供依据。

In the mine, the vast majority of spontaneous combustion fire was caused by goaf air leakage. Based on goaf air leakage on the condition of the wind, the application of different techniques and methods for testing were conducted, which can estimate the mine air leakage passage to determine the direction of the air leakage. The technology prevented goal coal spontaneous combustion and ensured the safety of coal mining working face production.
