摘要
根据正益煤业3下工作面的特点,系统的分析了3_下采空区的漏风通道,并根据对漏风通道的分析,结合漏风阻力定律,从增大漏风风阻和降低漏风风路两端的风压差的角度,提出了针对性的防治措施,保证了3下工作面的安全生产。
According to the characteristics of the third working face of Zhengyi coal industry,this paper systematically analyzes the air leakage channel of the third goaf,According to the analysis of the air leakage passage and the law of the air leakage resistance,from the angle of increasing the air leakage resistance and reducing the air pressure difference at both ends of the air leakage passage,The corresponding prevention and control measures are put forward to ensure the safety production of the 3 working faces.
