摘要
根据工作面支护强度验算悬移支架支护强度能满足上端头的支护要求，为降低职工劳动强度，提高回采效率将上端头铰接顶梁支护改为悬移支架支护。代替了以往的8～10棚一梁一柱铰接走向棚（排距1000mm，柱距500mm）支护型式。
According to the working face to support the strength calculation of cantilever supporting strength can meet the requirements of end support, to reduce the labor intensity of workers, improves the mining efficiency will end hinged support to the suspended support. Instead of the previous8~10shed beams hinged to shed （ row spacing1000mm,500mm ） supporting types.
