张集矿1413A工作面为巨厚砂岩直覆顶板工作面,是张集矿A组煤首采面。通过充分论证,该工作面设计、使用了ZZ18000/30/65D型支架。该型号型支架在国内为首次设计、首次使用。工作面回采期间,通过对矿压观测分析,论证了该套支架满足工作面巨厚砂岩顶板需要。%The 1413A working face of Zhangji mine is the roof working face of the thick sandstone, which is the first mining face of the A group. Through fully demonstrated, the ZZ18000/30/65D bracket is used in the working face design. This type of support is the first time design and use in China. During the working face mining, through the observation and analysis of the mine pressure, it is proved that this set of support meets the needs of the huge thick sandstone roof of the working face.
