综采工作面风压测定及采空区瓦斯渗漏分析

Analysis of Wind Pressure Measurement at Fully Mechanized Mining face and Gas Leakage in Goaf

以黄陵矿业集团二号煤矿207综采工作面为例,针对采空区的复杂漏风关系,通过布置风压测点,对207工作面进行了系统的风压测定,确定207工作面的风压分布规律,分析邻近采空区漏风与207工作面风压的关系,提出防止采空区瓦斯渗漏建议措施。

Taking 207 fully mechanized coal face of No.2 Coal Mine of Huangling Mining Group as an example,aiming at the complicated air leakage relation in the goaf,the paper determined wind pressure distribution law of 207 working face,analyzed the relationship between air leakage in the adjacent goaf and wind pressure of 207 working face,and suggested measures to prevent gas leakage in goaf by arranging wind pressure measuring point and carrying out systematic wind pressure measurement of 207 working face.
