摘　　要：煤层埋深浅,开采引起的地表剧烈变形严重威胁带式输送机的正常运行。针对地表变形数值大、时间短的特点,开创性地利用移动浮桥技术,治理带式输送机沉陷变形问题。移动浮桥构造简单,升高、移动灵活方便,通过工程应用,可实现地下工作面无限制条件安全回采。In shallow coal seam areas, the normal operation of the belt conveyor is seriously affected by the severe surface deformation caused by mining activities. The ground surface deforms dramatically within a short time period, to overeome this disadvantage, the mobile bridge technique is proposed to control the subsidence of the belt conveyor. The structure of the mobile bridge is simple, and it is also very easy to jack up or move the mobile bridge. Thus when the mobile bridge is used in engineering applications, it is safe and of no limitation to stope in underground coalface.
