综合考虑了奥陶系灰岩含水层富水性、承压水水头压力、井田构造复杂程度、底板隔水层有效阻水能力等4个影响因素,运用多源信息复合方法,构建了兖州煤田某井田下组煤底板奥陶系灰岩含水层突水预测模型,对该井田下组煤开采底板突水危险程度进行了评价；根据突水指数对16上煤和17煤底板突水危险性进行了分区；结果表明16上煤东部构造复杂区属于突水危险区,17煤东部和中部大部分属于突水危险区。评价结果为该井田下组煤开采的底板水防治提供了依据。
綜閤攷慮瞭奧陶繫灰巖含水層富水性、承壓水水頭壓力、井田構造複雜程度、底闆隔水層有效阻水能力等4箇影響因素,運用多源信息複閤方法,構建瞭兗州煤田某井田下組煤底闆奧陶繫灰巖含水層突水預測模型,對該井田下組煤開採底闆突水危險程度進行瞭評價；根據突水指數對16上煤和17煤底闆突水危險性進行瞭分區；結果錶明16上煤東部構造複雜區屬于突水危險區,17煤東部和中部大部分屬于突水危險區。評價結果為該井田下組煤開採的底闆水防治提供瞭依據。

The method of multi-originated information complex was used to build up a forecasting model for water inrush of the Or-dovician Limestone aquifer based on 4 influencing factors such as the water abundance and the water pressure of the Ordovician Limestone aquifer, the tectonic complexity and the efficacious ability of seam floor preventing water breaking. Then the subdivided zones of the risk of the upper No.16 and No.17 coal seams are obtained on the basis of water inrush index, which show that the northeast of the upper No.16 is under the danger of water inrush, as the east and the greater parts of the middle of the No.17. The evaluation result can offer some impor-tant reference for water inrush prevention.
