为了对斜井中段吊桥的使用情况和设计计算进行了解和分析,我们在斜井中段吊桥使用较多较早的某钨矿作了短期的参观学习。 某钨矿经过二十多年的使用实践证明,斜井中段吊桥是在斜井中段串车提升中联系斜井和中段运输平巷的一种好形式,与目前采用较普遍的甩车道相比,具有许多突出的优点:巷道开凿量小,而且由于交叉点处巷道宽度小,施工和支护都比较安全、方便。矿车通过吊桥时既安全又平稳,不会发生掉道事故,提升效率高。克服了钢丝绳通过甩车道时的磨损现象。吊桥本身结构也比较简单,使用、安装、维护都非常方便。该矿使用二十多年来,并没有因为吊桥本身的弊病而发生任何事故。
In order to understand and analyze the usage and design calculation of the inclined shaft middle suspension bridge, we have made short-term visits to the more inclined tungsten ore mines in the inclined shaft middle suspension bridge. After more than two decades of using tungsten ore, it has been proved that the middle inclined shaft suspension bridge is a good form of connecting the inclined shaft and the middle lane in the middle of the inclined shaft, which is more favorable than the current common driveway , Has many outstanding advantages: the tunnel excavation is small, and because of the width of the tunnel at the intersection, the construction and support are safer and more convenient. Mine car through the suspension bridge is safe and stable, no off-road accidents, improve efficiency. Overcome the rope wear phenomenon through the rejection lane. Drawbridge itself structure is relatively simple, use, installation, maintenance are very convenient. The mine has been in use for more than two decades and no accident has occurred because of the shortcomings of the suspension bridge itself.
