摘　　要：为更好地评判工作面能否实现安全开采,在系统收集现场煤矿开采底板突水资料的基础上,不仅采用突水系数、含水层富水性作为评价指标,还将突水水源按照其自新至老及其组合方式进行了分类并作为其中一个评价因子。采用单一Fisher评判和AHP赋权-Fisher评判方法建立工作面安全开采底板危险性评价模型并进行了对比,发现经过AHP赋权后的样本数据类内分布更加密集,其Fisher评判模型比单一的Fisherr评判模型具有更高的可信度。On the basis of systematic collection of coal mining floor water bursting data, not only adopting water bursting coefficient and aquifer water yield as evaluation factors, but also putting classification results of water bursting sources from new to old and combination method as one ,can use them to judge whether safe mining would achieve or not. Single Fisher evaluation and AHP empowerment-Fisher evaluation method based on working face safe mining floor risk assessment model were established and compared, can find that the latter would make sampled data more dense within class distribution and have higher reliability than the former.
