摘　　要：通过对圣华煤业1130工作面进行矿压观测,根据现场矿压数据,结合工作面实际地质情况,对支架发生受力不均匀,低头甚至后柱拉断等矿压显现现象和原因进行探究,分析了ZF3800/15/23型低位放顶煤液压支架失稳机理,在此基础上重新进行了支架选型,达到了良好支护效果。Through the Shenghua coal industry 1130 coal face to carry on the ore pressure observation, according to the field mine pressure data, unifies the working face actual geological condition, to the bracket occurrence subjected to the force uneven, the bow and even the rear pillar pulls the ore pressure manifestation phenomenon and the reason carries on the inquiry, analyzes the instability mechanism of the ZF3800/15/23 model low-position top coal caving hydraulic support, and then carries on the stent selection, then achieves the good support effect
