摘　　要：文章以大量的矿压观测数据揭示了气垛支架与围岩的相互作用关系和矿压显现特征。气垛支架具有初撑力大 ,与围岩接触面积大 ,载荷分布均匀 ,对底板比压小等突出优点 ,具有广泛的推广应用价值。The paper puts forward the relation feature between the reaction of air holder supports and surroundings and ground behavior. Air holedr has big setting load,has big contact area with surroundings,well distributed load,and low floor pressure ratio Air holder has the worth of wide use
