摘要
在收集肥城煤田180余件突水案例基础上,总结了该煤田的突水资料统计特征,并根据这些特征对肥城煤田深部开采进行了预测。提出了底板突水类型划分新方案,即将煤矿底板突水划分为:掘进沟通型突水、回采影响断层型突水和回采底板破坏型突水三大类。
Based on more than 180 cases of water inrush ng from floor, statistical characteristics of water inrush data in Feicheng coalfield are summarized and the water inrush type is predicated for the deep coal mining of Feicheng coalfield. A new classification of water inrush from floor is puts forward,that is,the water inrush can be didvided into three types：water inrush through path caused by heading,water inrush through fault induced bemiring,water inrush through broken floor due to mining.
