摘要
以8.8m超大采高液压支架为例,介绍了一种增压增力的新型复合护帮装置,该护帮装置既可以有效支护顶板,防止漏冒顶事故的发生,又具有较大的支护力,有效支护煤帮。为厚及特厚煤层开采提供了一种全新的护帮方案。
Taking the 8.8m super high hydraulic support as an example,introducing a new type of flipper mechanism with supercharging and increasing force.The flipper mechanism can support the roof effectively and prevent leakage of Roof accident.It also has large supporting force and effective support for coal side.It provides a new protection scheme for thick and extra thick coal seam mining.
