摘　　要：10煤是桃园煤矿三大主采煤层之一。距离其较近的太灰含水层,是10煤开采的直接充水含水层。在该含水层外围,以奥陶系为主的隐伏型碳酸盐类裂隙岩溶含水岩组,是其强大的补给来源,这对矿井安全威胁较大。采用突变学方法建立了煤层底板突水预测模型,对桃园煤矿10煤1026-21、041-2和1031工作面底板突水的可能性进行了预测,为桃园煤矿底板突水防治提供了理论依据。The No. 10 coalbed is one of three main mineable eoalhed of Taoyuan mine. The Archaean era limestone aquifer close to No. 10 eoalbed is the direct aquifer of it. The lie concealed carbonate cranny Karst water-hearing rock group which mainly are Ordovician distributing outer of the the Archaean era hmestone aquifer are the powerful supply of that. It is very danger to the mine production. In the paper,a cusp catastrophic model of forecast of water-inrush from coal floor is established,and the possibility of water-inrush from coal floor of the 1026^-2 ,1041^-2, 1031 workface of the No.10 eoalbed in Taoyuan coal mine are forecasted. The results provide theoretical basis for the prevention of the water-inrush from coal floor in Taoyuan coal mine.
