摘　　要：提出采场底板可划分为“四带” ,即矿压破坏带 ,新增损伤带 ,原始损伤带 ,原始导高带 .矿压破坏带、新增损伤带、原始损伤带的计算公式分别为 59.88ln(kmaxγH/σ1)、59.88ln(σIC/σ1)、h -(h1+h2 +h4 ) .根据“四带”理论 ,给出了一个较为完整的采场底板突水与否的判断方法 .Mining floor can be divided into four?zone,that is the zone destroyed by underground pressure,new damaged zone,original damaged zone and zone of pressure water inducing height.The formula to calculate zone destroyed by underground pressure,new damaged zone and original damaged zone are respectively 59.88 ln (K max γH/σ 1)、59.88 ln (σ IC /σ 1) and h-(h 1+h 2+h 4).On the basis of the “four?zone” theory,the occurance of the water inrush from mining floor can be judged.
