摘　　要：司家营铁矿北区位于滦河二级阶地和河漫滩上,矿区水文地质条件较为复杂,包含4个含水岩组。利用大井法和数值法对矿区各开采中段的涌水量进行了预测,结果证明两种方法计算结果较为接近,并且与矿山生产采场的实际涌水量相符,但数值模拟法相对误差更小,其计算结果可推荐为采场防排水设计依据。The north district of Sijiaying iron mine is located at the second terrace and alluvial flat of Luan river, the hydrogeologicial condition is complex containing four water-bearings. The results of water inflow quantity in the middle part of mines are predicted by using big well method and numerical simulation method respective- ly, and it proves the computed results of two methods are closed, and it consistents with the actual water inflow quantity of mine, but the relative error with numerical simulation method is smaller, its computed results may recommend for the design basis of water-proof and drainage system of mines.
