摘　　要：带压开采过程中,防止底板突水是安全生产的关键.为了解突水原因,通过对生产现场地质资料进行疏理,并运用地质理论和矿山压力理论,对拟开采的一1煤层突水危险性进行了分析,认为煤层直接底板本溪组铝土质泥岩隔水层厚度过薄,井田内小断层比较发育,间接底板奥陶系灰岩的富水条件是矿井突水的主要因素.分析结果可为今后预测一1煤底板突水危险性提供理论依据.It is important for security production to prevent the groundwater burst of bottom layer during mining carried pressure. In order to find out the water burst reasons, in the paper, groundwater burst of coal layer was discussed via the theoretic analysis of geological data in spot, exercised geological theories and mining pressure theories, and the water burst fatalness was analyzed on 一1 caol layer that be planed to be mined. The results show that the main factors of mine groundwater burst are thin thickness of isolation water floor of Benxi group gerlogy seam bauxitic muddy rocks, comparatively developed minet＇ield inner small fault, the rich water conditions of indirect bottom Ordovician limestone. It provides theoretic evidences for forecasting groundwater burst of coal bottom layer in the future.
