摘要
通过SF6示踪气体测定宏岩煤矿4405采空区的漏风量,并确定主要漏风方向,在此基础上优化宏岩煤矿4405采空区注氮工艺,使采空区的注氮能力分析更加准确可靠,确定采空区漏风量大小及方向对注氮效果的影响至关重要,从而确保采煤工作面的安全回采。
In this paper it measured the amount of air leakage in 4405 goaf of Hongyan Coal Mine through the SF6 tracer gas,and determined the major air leakage direction.On this basis it optimized the nitrogen injection process in 4405 goaf,which made the analysis of nitrogen injection more accurate and reliable.It was essential to determine the size and direction of air leakage in goaf,which affected nitrogen injection,thus ensured safe mining in the coalface.
