中文摘要：
针对煤层底板突水危险性难以准确评价的难题，在系统分析影响煤层底板突水主控因素体系的基础上，通过引入熵权理论以及未确知测度理论，建立了一种基于熵权一未确知测度理论的煤层底板突水危险性评价数学模型。并将该模型应用于大唐塔山煤矿8煤底板的突水危险性评价，得出的评价结果与实际情况基本吻合，为煤层底板突水危险性评价提供了一种有效途径。
英文摘要：
Aiming at the difficulties to evaluate the risk precisely, this paper introduced the entropy theory and the unascertained measurement theory and established a floor water inrush risk evaluation mathematical model based on entropy weight-unascertained theory. Then the model was applied in the risk evaluation of No. 8 coal floor water inrush of Datang Tashan Coal Mine, The evaluation results accorded with the actual condition, and the study provided an effective method for coal seam floor water inrush risk evaluation.
