摘要
为解决煤矿生产伴随巷道开启、关闭导致工作面通风状态发生变化进而影响矿井通风能力的问题,对凉水井煤矿4号煤层综采工作面巷道进行优化布置并采用双风机联合通风方式的手段进行改进。经评估,所采用的优化措施能够有效保证工作面通风能力的稳定性,保障了工作面的安全生产。
In order to solve the problem of unstable mine ventilat ion capacity due to changes in the working face ventilation status caused by the opening and closing of the tunnel in coal mine production,the improvement was carried out by optimizing the layout of the tunnel of the No.4 coal seam comprehensive mining working face and adopting the combined ventilation method of double fans to ensure the stability of the working face ventilation.It is evaluated that the optimization measures adopted can effectively ensure the stability of the working face ventilation capacity and ensure the safe production of the working face.
