摘要
根据薄煤层工作面开采需要,创新设计的薄煤层抬底机构,可以实现支架的抬底、回落动作,保证液压支架顺利移架和推溜,充分利用了薄煤层支架不多的结构空间,同时使支架具有足够的抬底能力。
According to the thin coal seam face,The characteristics of innovation design new thin coal seam the device carried ,guarantee that hydraulic support frame and push the slip, make full use of the structure of the bracket of thin coal seam is not much space, at the same time make stents has enough ability to lift the bottom.
