摘　　要：平煤集团高庄矿属于衰老矿井,主要开采阶段煤柱、大巷煤柱及对下分层进行复采,巷道顶板破碎,支护困难。通过采用悬移支架配合网下放顶煤采煤工艺,增加了工作面支护强度,提高了工作面单产水平,保证了矿井的安全生产,为类似条件矿井提供了借鉴经验。Gaozhuang mine of Pingmei Group belongs to the aging mines. It mainly exploits the stage pillars, the roadway pillars and re ：-exploits the lower bed. So the tunnel roofs are broken and the supporting is difficult. Through the use of the suspended stands with the caving mining technology, the surface support intensity has been strengthened. The per unit yields of the surface have been increased. And the mine production safety has also been ensured to provide referencing experience to the mines of similar conditions.

关 键 词：复采工作面 悬移支架 放顶煤 安全生产
