摘要
为解决轨距窄、井下车场对向错车困难、轨型和曲率半径不统一,大型设备运输车辆通过性差等问题,俄霍布拉克煤矿将井底车场巷道宽度由4.5 m刷扩到6.5 m,对向轨道中心距由1.4 m改为2.7 m,将轨距由600 mm改为900 mm。优化改造提高了轨道运输能力和效率,提升了轨道运输的安全性和可靠性。
To solve the problems of narrow track gauge,difficult apposition passing at underground station,inconsistency of track model and curvature radius and low trafficability of large transport vehicle,optimized transformation is implemented with the width of underground station roadway from 4.5m to 6.5m;center distance of opposite orbits from 1.4m to 2.7m and the track gauge from 600m to 900m,which has not increased not only the capacity and efficiency but also the safety and reliability of the track transportation.
