| 摘 要： | 为评价芦岭矿Ⅱ1018工作面开采危险性，结合大量钻孔资料、抽水试验成果、底板隔水层裂隙统计和水源识别判别，分析了太灰中1灰~4灰薄层灰岩的赋存特征，评价了工作面底板隔水层阻水能力，识别了Ⅱ1018工作面上位工作面（Ⅱ1016）的出水水源。研究结果表明：1）经Fisher判别分析，Ⅱ1016工作面出水水源为灰岩水；2）1灰到4灰各单层灰岩逐渐增厚，富水性增加，但灰岩作为一整体含水层时，其富水性有随深度弱化趋势；3）10煤底到1灰隔水层厚度稳定，裂隙发育较弱，富水性差，具备有效隔水岩层的基本条件。

| Abstract: | Combining with drilling data, pumping test results, fracture statistic of floor aquifuge and water burst?ing source recognition, this paper analyzed occurrence characteristics of taiyuan group's 1st and 2nd thin-bedded limestone, evaluated water-resisting ability of floor aquifuge, identified the source of inrush-water in Ⅱ1016 coal face.The results shows :1)By using fisher discrimination analysis method, the source of water irruption is limestone water.2)From 1st limestone to 2nd limestone of taiyuan group, the thickness of every single layer is thick?ening ,the water abundance is increased, however, seen as one aquifer of taiyuan group, its water yield property shows a weakening tendency.3)The thickness of aquifuge between the bottom of 10th coal and the top of 1st lime?stone is stable, and its crack development and water abundance are weak. |
