摘要
ZPY4800/14/28QS液压支架在大倾角、大仰采、“三软”煤层、分层(铺网)的工况条件使用中,存在支架陷底、移架“耙底”、后铺网无安全空间及架前上网等问题,通过对支架“刨齿”和尾梁的改造,克服了上述问题。
During the operation of ZPY4800/14/28QS hydraulic support under the conditions of large dip angle,large overhead mining,three soft coal seams and layered(net laying),there are some problems,such as the support sinking bottom,the moving frame"rake bottom",the back net laying without safety space and the grid before the support.The above problems are overcome through the transformation of the support"planer"and tail beam.
