摘要
阳煤一矿北翼采空区出现漏风和CO超标后,采取密闭和调整风量等措施效果不佳,通过调整主扇和担负的通风区域,改造南翼回风系统,并进行回风系统巷道降阻,排除了安全隐患,确保了矿井安全生产。
Sealing and air volume control cannot solve the problems of air leakage and CO overrunning in Northern goaf in No.1Colliery of Yangquan Coal Industry Group Co.,Ltd..The author presents the transformation on the southern air-return system by adjusting the main fan and ventilation area and reducing resistance of ventilation roadway,which can eliminate the hidden hazards and ensure the safety production.
